To work in the world is hard, to refrain from all unnecessary work is even harder. - Nisargadatta Maharaj

There is nothing wrong in the idea of a body, nor even in the idea 'I am the body.' But limiting oneself to one body only is a mistake. In reality all existence, every form, is my own, within my consciousness. (…).

The world and the mind are states of being. The supreme is not a state. It pervades all states, but it is not a state of something else. It is entirely uncaused, independent, complete in itself, beyond time and space, mind and matter. (…) it leaves no traces. There is nothing to recognize it by. It must be seen directly, by giving up all search for signs and approaches. When all names and forms have been given up, the real is with you. You need not seek it. Plurality and diversity are the play of the mind only. Reality is one.

If you want to know your true nature, you must have yourself in mind all the time, until the secret of your being stands revealed.
