We experience life in tiny slices, but all of it takes place in awareness. This is in our aware ness as the known and that unknown are both in our awareness. And the vast is also in our awareness as a vague unknown, unthought of,. unseen, unheard, unremembered, ununderstood, untasted. So everything in life is in o ness, as known as unknown. Then you'll begin to see what a dweit ovedantais saying is making more sense. If you only think as knower, you'll see, i am only id. The rest is just outside.
Inspired by the 15th chapter of the Ashtavakra Gita, Swami Sarvapriyananda gives a discourse on the nature of the Self.
