here are my answers:
1) I do a simple test of saying I´m and observing. Immediately a strong energy current comes and I feel strong, full. Then I do a different test: I´m looking where is this I and cannot find it. It is a vast empty space. Emptiness. The budists have emptiness. But this is only one side of the coin. Other side of the coin is fullness. I noticed that Liberation unleashed emphasizes only emptiness.
2.)Baby is a vast ocean of unconditoned self. Parents raise us up and feeling of I and my toys, my bicycle... is imprinted on a child and we become conditioned. We get used to behave like conditioned self. With using I,my.. we give energy to this thoughts and they get stronger, illusion gets stronger. Than comes Liberation Unleashed and remembers us that we are more than just a thought "I". As Mr J. Krishnamurti said:"When you are aware of your conditioned self, you will get to know your whole consciousness. Consciousness is whole field on which a thought is working and where the relationships exsist. All motives, intentions, wishes, comfort, fears, expectations, aspirations, sorrow, joy are in this field. And this consciousness where there is no more choice and judgement, will maybe open the door and you will find out that there is a dimension without opposite and without time." And I feel more and more like that.
3) I´m more calm, more at peace with myself, like whole. Before I felt like there are different parts of me inside me and one was going left while the other was going right and this caused unrest inside me. Now I feel like beeing one with myself.
4) Observing this separate "I" and knowing that it is my energy trapped in illusion. Than illusion disappeared and separate "I" merged with main "I".
5) No. Life just flows through me.
