There is no effort that we can make to still ourselves. True stillness comes naturally from moments of solitude where we allow our minds to settle. Just as water seeks its own level, the mind will gravitate toward the holy. Muddy water will become clear if allowed to stand undisturbed, and so too will the mind become clear if it is allowed to be still.
Time is endless in thy hands, my lord. There is none to count thy minutes. Days and nights pass and ages bloom and fade like flowers. Thou knowest how to wait... At the end of the day I hasten in fear lest thy gate be shut; but I find that yet there is time.
