As a man changes his raiment for a feast, so is a man changed in his heart who prepares himself for the holy act of confession.  It is indeed like a changing of raiment to lay off manyness, in order rightly to center down upon one thing; to interrupt the busy course of activity, in order to put on the quiet of contemplation and be at one with oneself. And this being at one with oneself is the simple festival garment of the feast that is the condition of admittance.  The manyness, one may see with a dispersed mind, see something of it, see it in passing, see it with half-closed eyes, with a divided mind, see it and indeed not see it.  In the rush of busyness, one may be anxious over many things, begin many things, do many things at once, and only half do them all.  But one cannot confess without this at-oneness with oneself....But he that in truth becomes at one with himself, he is in the silence.  And this is indeed like a changing of raiment: to strip oneself of all that is as full of noise as it is empty, in order to be hidden in the silence, to become open.

- Soren Kierkegaard, Purity of Heart
