"Self-enquiry", also called ātma-vichār or jnana-vichara is the constant attention to the inner awareness of "I" or "I am".

In the presence of this Sage one felt security and inward peace. The spiritual radiations which emanated from him were all-penetrating. I learnt to recogn ise in his person the sublime truths which he taught, while I was no less hushed into reverence by his incredibly sainted atmosphere. He possessed a deific personality which defies description. I might have taken shorthand notes of the discourses of the Sage: I might even print the record of hi s speech: but the m ost important part of his utterances, the subtle and silent flavour of spirituality which emanated from him, can never be reported. If, therefore, I burn literary incense before his bust, it is but [a] mere fraction of the tribute I ought to pay him. -- by Paul Brunton
