athāto brahma jijñāsā
“now is the time to inquire about the absolute truth”
The Vedanta-sutra (1.1.1) states, athato brahma jijnasa: “Now one should inquire about Brahman – The absolute truth, the transcendental, spiritual nature”
SB. Canto 4, Chapter 25, Text 5, Text26, purport:
The first aphorism in the Vedanta-sutra is athato brahma jijnasa. In the human form of life one should put many questions to himself. In the human form of life one should be intelligent enough to ask what he is, why he has come into the world, what his duty is, who is the supreme controller, what is the difference between dull matter and the living entity, about his spiritual identity. These are inquiries about atma-tattva–self-realization.
