Srimad Bhagavatam 1.1.11

There are innumerable spiritual texts, but they do not talk of one conclusive method, instead they describe a large number of actions. Furthermore, they are so large that it is time-consuming to listen to even a small portion. You have everyone's well-being in mind. Please use your intellect to extract their summary and, for the salvation of all beings, describe it to us, the devotees, by which we can purify our antahakarana or mind || 11 ||
