Unreal world

For last couple of days, I have a unique doubt? Do we really exist? Who is this - "I" ? The name, the body - is that all we are or is it just a collection of the memories of the past. When we say -"I", do we mean just those memories, which literally has NO MEANING now, except to remember the good times or the bad times, we have experienced in the past and on which basis, we try to spoil or make happy our present also. Do we actually ever give a chance to ourselves to experience the present fully? Do we really live or do we live thru a filter of past memories?

And who breathes life in us - we ourselves or something else? Do we breath to remain alive or life just comes inside the body as a vital force to keep the body alive, till it decides otherwise? Are we individual or are we just part of a life, which is experiencing itself in diferent hue and colours, and we spoil it up by adding this element of "I". Where this "I" fits, if it is not the one who breathes, and the one who digests the food to keep us alive and healthy. Is not it a separate mechanism, which has its own intelligence ? Have you ever realised that the two things, which keep us alive, that is breathing and digesting is beyond our limits, and it happens on its own.

Once you realise this, you will feel that you are just a medium in this experience of life which is experiencing itself. There is no question of good or bad, as life wants to experience everything. We unnecessarily get happy or upset by sequence of events, thinking that we are important and it is our life, whereas actually it is just life, not your or mine. We are all different forms of the same life, which you might call Awareness, Consciousness or God. But since we don't realise it, we have a very different perception of this life, full of happiness, sadness and what not !
