Here is a great and profound Talk by Swami Sarvapriyananda who patiently, taking all the time in the world and repeating himself for the sake of the audience, explains the process of perception and realization of the Self. The Video is over 1 hr 39 mins. It is enough to watch the first 56-57 mins. The rest is Q&A; a couple of questions are good.
The Swami quotes “अनुभवमात्रं परं ब्रह्म” but was unable to recollect the source. With a slight variation, the quote, IMHO, is from Yogavasishta. The full verse is:
अदृश्यो दृश्यते राहुर्गृहीतेनेन्दुने यथा |
तथाऽनुभवमात्रात्मा दृश्येनाऽऽत्मा विलोक्यते || — verse 3, sarga 118, Ch 6, book 2, Yogavasishta.
Meaning: The invisible soul is known in the knowable mind, which is actuated by it (the soul); as the invisible node of Rahu, becomes visible to us in the eclipse of the moon (which is affected by it). —English translation by Vihari-Lala Mitra (1891)
It’s a Video to immerse oneself fully; so I suggest, you ditch your coffee cup too, or finish the coffee before you click “Play.” Enjoy.
