Do thou also then groan, even as that holy one, I forbid it not. “Rend,” as the prophet commanded,“thine heart, and not thy garments.” Out of deeps call upon God, for it is said, “Out of the depths have I cried to Thee, O Lord.” From beneath, out of the heart, draw forth a voice, make thy prayer a mystery. Seest thou not that even in the houses of kings all tumult is put away, and great on all sides is the silence? Do thou also therefore, entering as into a palace,—not that on the earth, but what is far more awful than it, that which is in heaven,—show forth great seemliness. Yea, for thou art joined to the choirs of angels, and art in communion with archangels, and art singing with the seraphim. And all these tribes show forth much goodly order, singing with great awe that mystical strain, and their sacred hymns to God, the King of all. With these then mingle thyself, when thou art praying, and emulate their mystical order.
