I went back and listened to the “experiencing self” vs the “remembering self” multiple times. It never occurred to me that fulfillment in life can come down to having a rich remembering self, and that this richness sometimes requires experiencing some pain, discomfort, or an effort of some kind. Wise words to live by.

[@rohs_vivek]

"was planning on it 😅"

[@sylviaAguenther-zc9lg]

Hi Elle-💕👍your post,but I feel I should clarify to U that many of us who have experienced this such fulfillment as U & Mr Charan claim u have to experience to have a more rich life,pain than richness of the soul,sucks! 🤔sorry✌️🦋

I am not all the way through this yet, but if you are reading this comment, know that the value of this podcast is immense. Just the first 30 seconds alone where Charan explains how memories often cannot be trusted is an absolute game-changer. It is a direct path to the present moment - knowing that the past (even your own memories) may very well be an illusion. It helps you be here and now - allowing you to get the most out of each moment in life. Lex, thank you for your great work, and I’m glad you are back from your trip.

coming from a rough childhood I figured it out on accident or by my own nature. When you look at the past, keep the lessons, but put yourself in the shoes of the "actors" in your memories. Give them noble reasons instead of evil one. It help memories turn into wine instead of vinegar over the years. We are all assholes, we just only see it in others

I enjoy the way Lex conducts his podcasts, great questions and follows up with the reason why he asked them. By far my favourite podcast interviewer.

[@idatong976]

It's fascinating to listen to Charan Ranganath about his deep knowledge and wisdom on memory and life in general. I love his scientific explanation of memory and the philosophy behind the theory. What a beautiful conversation this is! As always, I learn so much from you and your brilliant guest! Thank you Lex! ❤

[@Luvalways3]

Thank you Charan and Lex. Excellent conversation! The memories of my late father are precious to me. I'm thankful for our complex brain and its ability for the gift of recall. Human memory and emotion make us unique creatures on the earth!

[@CapitanFantasma1776]

I used to record my dreams. After years of doing this, I realized my Deja Vus were me dreaming the future. I couldn't control any of this. It just happened. Thanks!

[@idontknowyetwhoiam]

I've started to have similar experiences/realizations. Part of me thinks it means I'm going the wrong way because if the deja vus are "dreams of the future" it means it's already happened so why go through the loop again? Idk I just don't wana be fucking myself somehow. How do you feel about it?

[@asdaszxczxczx314]

same here

[@nosmartyr]

​@@idontknowyetwhoiam in the collapse of dimensions, free of time and space, all experience happens at one point, at once. The bible commands us to pray as if we are in that moment experiencing our prayer being answered not just as a way to raise vibration by being in gratitude, but to resonate at the frequency that matches our desired future self & future timeline. It is by quantum leaping thru these doors that we can and do experience miracles.

[@iamatlantis1]

It's strange to really allow for, but I think it has something to do with how time is apparently just an illusion? Everything that has happened and will happen has technically all happened at once. When my Mother died 3.5 years ago, the night before I had this really strange experience where in the middle of driving down the road I was hit with the super strong urge to call my Mom. It felt very sad. This was less than 24 hours before she died. Now for reasons I won't go in to here I hadn't been speaking with her for about 4-5 months. As a result of this feeling I stopped what I was doing and went home with the intent to call her. I got home and I didn't call her. The next day I get the call that she had passed. Someone or something some how knew, myself maybe even, or she herself already from the other side tried to warn me. It's now one of my biggest regrets that I didn't call her and get to talk one last time. It's possible that had I called her, the series of events that let to her death may have been altered and she'd still be here. What or whom was warning me and trying to get me to call her the night before? Was it me already knowing what was going to happen? Similarly to your deja vu dreams?

[@rhiannablumberg4803]

omg YOU are the 1st and ONLY other person besides ME that has ever understood or even SAID this!!! wow!!!! that's EXACTLY what my deja vus have been since I was in high school!!! so cool to know I'm not alone!!!❤❤❤😊😊😊

Lex your first comment about memories being a source of happiness like fruit to a tree, was extremly beautiful and inspiring, i feel your wisdom as you came out from the jungle, love you brother

[@sdvanon1285]

I realized many years ago that time is not linear in our experience of life. Past, present and future interact and effect each other. In the present, we are always recreating the past and creating/changing the future. A 'good' therapist can use this complex interaction to help a person; a 'bad' therapist can use this to manipulate a person (the classic example being false memory syndrome). Since we are not alone in the universe, our experience of past, present and future interacts with and is influenced by the experiences of others, individually and as groups. Humans are amazing because somehow we live together, and often achieve great things together, and manage to love, dance, cry, work, play together, even though our perceptions and experience of past, present and future (individually and as groups) are always changing.

Samantha says "the past is just a story," she means that our memories of the past are like stories we make up in our minds. They're not always exactly what happened, but they're the way we remember them and tell them to ourselves. It's a reminder that our memories can be flexible and might not always be 100% accurate.😮

[@stevengill1736]

For some reason I ran away from home when I was 3 or 4 - I can still remember it perfectly at 70. I wasn't unhappy, simply curious. My folks were distracted, so me and the dog ran out the door at sunset, me in my pajamas, the dog excited as could be. We wandered around the neighborhood 'till it got dark, and I was wandering along the main road with lots of traffic on it until my dad picked me up, very angry of course! Such a strange thing to do - I wasn't mad, just excited to be out exploring. Must have been a strange sight for people driving by! NB : Lex, I too have that problem remembering names, perfectly explained by your guest (what was his name again? 😊)

[@crbradbury8282]

I really enjoyed reading your comment! Thanks for it friend. Glad your dog tagged along...that was cinematic. 🤠

[@HB-iq6bl]

I did the same , left home at 4, went down to the bush by the creek and thought I'd live there.im not sure if my dog stayed, too many weeds and dampness.when she left I stealthily snuck home and announced I had returned, my mother and her friend laughed at me. I was expecting to be welcomed and loved with concern.

[@mlpetty]

I’m rereading Man’s Search for Meaning right now and I really loved your question about how to maximize the enjoyment of a memory. In suffering, the parts of us that remember beautiful experiences can help us find so much meaning in suffering and experiencing the cold contrasts of life.

[@varunmeena4739]

Same, I'm also reading this book. It's a very nice book. Made me think about my own life's meaning. I think suffering is real and we all should try to minimise suffering from our life(s) as well as from other's people life(s). (Animals also)

[@lizgichora6472]

Thank you very much Lex Fridman and Dr Charan Ranganath.

[@westonlong]

This was fascinating in so many ways. As a person born with epilepsy I appreciate the Deja Vu conversation and memory issues epilepsy can cause. I have big gaps in my memory and oftentimes I feel people want me to fill it in with their version of reality not really an objective one. Now I see we all remember things differently and the memories are loose somewhat.

[@catalhuyuk7]

I just checked your channel this morning to make sure you made it out of the Amazon and maybe posted a video and here you are! ♥️🇨🇦

[@CHXFIT95]

Everything he is saying is spot on. I would also strongly agree the self is a continuously evolving construct. I think this is one of the factors of regret because we are different version of us tomorrow then we are today, good or bad, that mind state or construct around who we are always gets altered making us very different person who we are today vs 20 years from now.

I once heard David Wolpert refer to this as "retrodiction". We don't recall the past as a matter of fact, we retrodict the past. In other words, our minds retrodict the past just like we predict the future. The only difference is, we have far more information on hand when retrodicting the past.

I have epilepsy and right before I have a seizure I get de ja vu, except its like 20-30 of them in a row and usually will be something in the immediate future (seconds ahead) or a thought that I know will lead to another thought that will lead to another. When it’s coming on, I feel intense anxiety and nervousness.

[@westonlong]

Me too, I also smell like a burning tinfoil or something right before it happens telling me I need to immediately lay on my side, and if possible on my bed or something soft.

[@raens9256]

"The self is an evolving construct." Yes. Yes yes yes. A thousand times over yes. And, importantly, the self is a very social entity that we are not accustomed to thinking of as social. Which made this conversation a great listen for me. As always, I find that many perceptions of the Buddhist approach to attachment, non-attachment, and their relationship to suffering are somewhat nihilistic as opposed to my lived experience, but I really appreciated how various ideas in here not only connected to my social psych education but also related to that foundational idea of interconnectedness I find in Buddhism. (World and drops of dew and all that rot.) Thank you, Lex. This was great.

I always thought we just have only a certain amount of working memory, and you are learning and gaining information at such an extraordinary pace in the first years of life that the human brain has to prioritize, the memories it retains in order to retain the most important.

[@tonyhill2318]

Far more than a source of happiness, our memories are the source of misery, worry, and torment. We're incessantly run around and mentally controlled by it. Even remembering happy times is most often quickly followed by sadness of what's gone or how it all went wrong. Let's be honest with ourselves.

About Imagination vs Memory really clarified my thinking about hindsight. For a little while, I've been thinking that people punish themselves about not doing something in hindsight, but very often forget what reason they had had to do the action in the first place which could be perfectly reasonable. This could be a link to "remembering" the past being a hallucination (imagination) instead in which we omit the past mindset information. Journaling could really be powerful.

This intrigues me. Could you elaborate more? How do you mean reset? To what what end? If you still remember enough about the photos to add captions. Or perhaps its darker than that.

Excellent summary! Much appreciated

[@psylocyn]

I have a form of Temporal Lobe Epilepsy that has intense, frequent Dejavú as one of the main symptoms.. I’m interested to see what he has to say

[@TrexikLP]

This podcast made me think about my life and personality, my brain XD The fact Charan mentioned how eyes and brain work, I started running my eyes around whole room :D Love those podcasts!

[@7uhv]

Brilliant episode ,will listen to this again and again!

[@clairek8651]

Lex, the 5 o’clock shadow looks handsome on you 👌🏽 And I hope to one day have someone like you in my life 😊 Your morals and ethics are what I admire the most. Your characteristics as an individual, from what I have briefly seen on this channel, are exactly what a man can be defined as. A true gentleman. And I hope to one day have someone like you in my life.

[@sylviaAguenther-zc9lg]

Hi,You sure are a lovely girl, I'm sure with such a nice compliment he 'd be a fool not to give U a shout out.Good luck💖😉

[@yvealeciasmith]

Such a fun conversation and interesting topic. Immediately wanted to be friends with Charan. Really compelling to think of how, through the mechanism of memory, the past becomes the future (until it doesn't). Also, I have a habit of choosing to do things that are absolutely a 'pain in the ass' in the moment for the sake of the memories, and my first thought when things go very wrong is 'ooh, this is gonna be a good story', so I shall skip away merrily with my validation, thank you very much!

[@hsiaowanglin9782]

Not from my memories, but through some media every day in Taiwan, so I watch that every couples days upgrade information!

[@Dr_Varghese_Manappallil_Joy]

3 Hours of absolute Bliss..Super Thanks Lex...!

[@jdt2003]

In the last 4 years, normally after a run, I will get Deja Vu. It normally happens when I see a scene that I've seen before. I notice the onset with a pleasant feeling - then it feels like i'm in a dream. I smell some type of copper? - a smell which I enjoy. It lasts for about 2 minutes then fades.

[@anshdeshwal7004]

Lex please get someone to about the developments in BCI especially neuralink

2:18 A clock that is watched for 1 minute feels slow yet when you're preoccupied to something else a minute moves fast This phenomenon is one of two things attention makes you more present to the passage of time Or while you are doing something you are unaware of time When time moves slow you are thinking faster When time moves fast your brain is working on other activities or slower

[@kev2582]

Amazingly knowledgeable and easily elaborated. What is interesting is neuroscience is no closer to explain how brain works than decades ago - there is very little new in what’s discussed. New approaches are needed.

[@Natalieboonelove]

Woah I just opened my KZbin to see my Psychology of Memory teacher back at University on the Lex Fridman Podcast! Wild. Hi Dr. Ranganath!

[@yvonnehyatt8353]

Very good Lex :This would be a good video for public schools teachers and parents to learn.

[@kellysownytube1599]

Thanks Lex, really enjoyed this podcast on memory with Charan Ranganath, very interesting. Could you look at getting on Prof Sam Vaknin soon, he has a PHD in Physics and can talk about AI, phychology etc

[@mojtabaazeez5346]

8:02 that was one of the best motivation sayings that I've ever heard!!

[@Pikminiman]

This is an especially good interview. Thanks for sharing, Lex.

[@davidharman1]

The 'owner of a lonely heart' reference was gold!

[@josephvalentine-c7d]

The feels on this one man.

[@johnchappell4492]

Yes !

[@diraziz396]

Great suggestive explanation on why we don't remember early memories 14: 45

[@Hieye.]

Peace and Love to you all ♥️

[@Phatxual]

I'm beyond glad to have clicked on this vid! Charan is a super fascinating chad💯🧡

[@Aphrodite7008]

Beautiful Lex! Yes, some memories will never fade 💕

[@flflflflflfl]

Please, please, PLEASE get Iain McGilchrist on the podcast!

[@funobruso]

Great guest, Lex! It was a pleasure

[@lorirodgers9474]

Thank you both for this lovely mind stretch.

[@joshviggiani9844]

"I have to think about this, let me get back to it." Oh I felt that. For me think it might be because of something like PTSD because ive messed up far too many times in my life just by opening my mouth, or doing things.

[@listeningprofano]

It's the second time in a row that someone says Lex is going to attack him. In the previous podcast, it was Paul who said it

[@jasonfay2250]

Talk about bringing back memories. Lex mentions James Brown and Charan calls up the SNL hot tub skit with Eddie Murphey. HAven't thought about that in years.

[@jamiechristoffersen1879]

What an amazing interview! As a Waldorf teacher we focus on recall and rhythm to improve memory. I learned the importance of this work! ❤Thank you fine gentlemen. 🫡

[@Appleloucious]

One Love! Always forward, never ever backward!! ☀☀☀ 💚💛❤ 🙏🏿🙏🙏🏼

[@thatotherjohnc]

Great guest, very interesting, thank you Lex and Charan!

[@AaronAsherRandall]

So many “holy shit” moments in this discussion. I’m going to try and listen to Lex Friedman at least 3 or 4 times a week from now on. I’m a student of computer science and spend a lot of time coding and working on applications. So much talk about the FMRI data just got my brain spinning on potential apps that we could build to better understand our brains and how they work on a deep level.

[@rustywantstowin]

Scars are great for conversation. I look each one as it's own individual conversation piece...

[@torbjornolsson4622]

Wow, this was soo interesting! And Charan was such a fun and great guy!
