The word Power Stone is a word used in Japan.
It often refers to semi-precious stones rather than precious stones.
Stones have been used in various ways around the world since ancient times as fortune telling, magic, and amulets, but in recent years, in Japan, it is said that you can get power by wearing a stone or placing it close to you, and stone accessories are popular.
I think the reason behind this is that Japan has had the idea since ancient times that God dwells in all natural things, called "eight million gods."
Of course, it also resides in stones.
In Japan, there are many people who can accept the idea that stones also have mysterious energies and powers that transcend human knowledge.
I think that the word "Power Stone" was created from such a Japan way of thinking.
~About purification~
By wearing the stone or placing it close to you, you can receive good energy, but it is said that the stone gradually absorbs the bad energy.
The act of getting rid of it on a regular basis is called "purification."
"Purification" is also performed to remove bad energy floating in the space.
In Japan, "purification" is important.
It also refers to actually removing dirt or cleaning, but it can also include ritual things.
Even at shrines, the act of cleansing is performed during ceremonies.
"Exorcism" has a similar connotation.
"Exorcism" also means to exorcise evil spirits, but it also includes the meaning of removing bad energy that is invisible to the eye.
In Japan, "purification" and "purification" are very important.
When cleaning at home, in addition to the purpose of physically cleaning the room, it also has the purpose of getting your mind in order and removing bad things that are invisible to the eye.
"Purification" is an act that also leads to these.
