Instead of wasting time acquiring borrowed knowledge from books, utilize that time in the practice of yoga. If you know who you are, you will come to know everything. There is nothing in this external, manifested world which is not within you. Believe my words; there is no truth without, because your Atman is ‘sarvabhutatman,’ the Atman seated in the hearts of all creatures. In you is the dormant seed form of all the knowledge, power, and wealth of this entire creation. Why should you leave the diamond and waste time on pieces of glass?
