In plain words

Now there are three meditations of the all-conquering Kauṣītaki. Having put on the sacred thread and sipped water, having thrice poured out a vessel of water, let him worship the rising sun with these words: "Thou art the remover; remove my evil." Then, with the same procedure, when it stands in the middle: "Thou art the up-remover; remove my evil." Then, with the same procedure, when it goes to its setting: "Thou art the gatherer-away; gather away my evil." Whatever evil he does by day and by night, it is gathered away.
