Acharya Prashant defines Satsang as being in the right environment and realizing what affects the mind to act accordingly. He explains that the mind must be provided with the right food, companions, books, and activities. The 'right' environment is one that does not unsettle the mind or load it with ideologies, thoughts, and opinions. A true companion or friend is someone who is not eager to impose their own mental burdens or 'dirty linen' upon you, as the nature of the self is to remain settled and peaceful. He emphasizes that one should assess their environment by whether it brings peace or causes disturbance, ambition, and memory-driven burdens. Harmony, he notes, is not enforced uniformity but a celebration of diversity and oneness.
