Everything known, nothing remembered.

Sri Nisargadatta Maharaj

Take dream for an example. In a hospital there may be many patients, all sleeping, all dreaming, each dreaming his own private, personal dream unrelated, unaffected, having one single factor in common - illness. Similarly, we have divorced ourselves in our imagination from the real world of common experience and enclosed ourselves in a cloud of personal desire and fears, images and thoughts, ideas and concepts.

This I can understand. But what could be the cause of the tremendous variety of the personal worlds?

The variety is not so great. All the dreams are superimposed over a common world. To some extent they shape and influence each other. The basic unity operates in spite of all. At the root of it all lies self-forgetfulness; not knowing who I am.

To forget, one must now. Did I know who I am, before I forgot it?

Of course. Self-forgetting is inherent in self-knowing. Consciousness and unconsciousness are two aspects of one life. They co-exist. To know the world you forget the self - to know the self you forget the world. What is world after all? A collection of memories. Cling to one thing, that matters, hold on to 'I am' and let go all else. This is sAdhanA. In realization there is nothing to hold on to and nothing to forget. Everything is known, nothing is remembered.
