Finite experience, which is measured in terms of past, present and future, cannot be transcendental. Concepts of time are illusory, for they have no permanence. The present, immeasurably small and fleeting, cannot be grasped. Past and future are non-existent in the present. We live in illusion.
The meditative state transcends all such limitations. In it there is neither past nor future, but only the consciousness of "I am" in the eternal NOW. It is only possible when all mental modifications are stilled.
The closest analogous state that we can experience is deep sleep, in which there is neither time, nor space, nor causation. Meditation, however, differs from deep sleep, for it works profound changes in the psyche. By curbing and stilling the oscillations of the mind, meditation brings mental peace.
