At the extremity of prayer words vanish, or rather the "silence-become-word" surpasses all that can be uttered. Prayer becomes the silence of Love, and this silence reveals the "I" in its deepest aspects; and, should words suddenly arise in prayer, we must regard them as fruits of love that send us back to silence.
Serious spiritual practice is more than serene walks in the woods, lit candles and incense. You have to be committed. Your have to be willing to enter into your own darkness and transcend it.
