The only requisite necessary is for each one to be willing to let God come forth.
~ Baird T. Spalding
Silence is the matrix from which word is born, the home to which word returns through understanding. Word (in contrast to chatter) does not break the silence.
In a genuine word, silence comes to word. In genuine understanding, word comes home into silence. For those who know only the world of words, silence is mere emptiness. But our silent heart knows the paradox: the emptiness of silence is inexhaustibly rich; all the words in the world are merely a trickle of its fullness.
