Bhaktajan,
I have only a very dim understanding of what Advaita "is", if it is actually anything.
Primarily, I see Advaita in one sentence : Everything is one thing. There is nothing seperate from anything else, because there is no "thing" apart from "one thing". All life is equal.
Sequentially, I have difficulty in seeing how individual consciousness and Consciousness are one and the same. I am not agreeing or disagreeing with "Thou art that", merely expressing my confusion about what happens. Is the individual self lost ? I have experienced some moments of a deep silence, some moments of a deep freedom and can distinguish between idle and useful thought.
I do not understand karma clearly and am unsure whether or not I accept its validity. The same goes for reincarnation. If there is no seperate self, then what keeps returning ?
Overall, I am at the level of trying to observe myself thinking. I am taking this very slowly and my attitide is very much "this is what I have found to work for me so far".
It is a very rich and full philosophy and is in accordance with science , in particular physics.
