I know my comment might come across as just another fanboy praising Alakh Sir, but I have to say that his explanation of the concept was truly exceptional. I searched extensively on KZbin for an explanation in Hindi, but none of them came close to the level of clarity and understanding that Alakh Sir provided. His way of simplifying complex ideas and presenting them in an easy-to-understand manner is truly remarkable.
