We live in succession, in division, in parts, in particles. Meantime within man is the soul of the whole; the wise silence; the universal beauty, to which every part and particle is equally related; the eternal ONE.
So, to meditate is to purge the mind of its self-centered activity. And if you have come this far in meditation, you will find there is silence, a total emptiness. The mind is uncontaminated by society; it is no longer subject to any influence, to the pressure of any desire. It is completely alone, and being alone, untouched it is innocent. Therefore there is a possibility for that which is timeless, eternal, to come into being. This whole process is meditation.
When you inquire 'Who am I?' if you are honest, you'll notice that it takes you right back to silence instantly. The brain doesn't have an answer, so all of a sudden there is silence.
