Acharya Prashant explains the concept of 'Prajnanam Brahma', defining 'Prajnan' as the peak of understanding or pure consciousness that transcends ordinary knowledge. He states that Brahman is not separate from one's own realization or understanding. Therefore, there is no need for external worship or even formal Brahma-vidya; instead, one needs meditation, which acts as a bridge between the mind and the soul. While ordinary knowledge is fragmented and diverse, true understanding or 'Prajnan' is singular and beyond numbers. It is the state where knowledge becomes so subtle that it disappears, and what remains is the radiance of Brahman.
