Death is a dignitary who when he comes announced is received with formal manifestations of respect, even by those most familiar with him. In the code of military etiquette silence and fixity are forms of deference
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.
We must leave the entire collection of conditioned thought behind and let ourselves be led by the inner thread of silence into the unknown, beyond where all paths end, to that place where we go innocently or not at all, not once but continually.
