Jnana yoga

Jnana is the greatest purifier. There is no salvation without knowledge. knowledge of atman destroys ignorance, pain, sorrow and stops the wheel of births and deaths.

Attain this knowledge through satsanga, service of guru, study of vedantic books, hearing of srutis, reflection and constant meditation.

sorrow is for one who has the notion of self in the body, not for the sage who identifies himself with the all-blissfull atman.
