Those who are ignorant of the supreme purpose of life will never be able to attain nirvana (liberation) in spite of their observance of the vratas (vows) and niyamas (rules) of religious conduct and practice of shila (celibacy) and tapas (penance).
By self-study, by observing, by being hollow and empty, you become a channel - you become a part of the Divine. You are able to feel the presence of Divinity. All the different angels and devas, all these different forms of our consciousness, start blossoming.
The Self, having in dreams enjoyed the pleasures of sense, gone hither and thither, experienced good and evil, hastens back to the state of waking from which he started. As a man passes from dream to wakefulness, so does he pass from this life to the next.
