Having folded his hands in reverence, he should worship the triad of gurus on the left: / the guru, the paramaguru, and likewise the parāparaguru. / On the right side, he should visualize Gaṇeśa, and on the crown of the head, the deity. / Then, having purified his hands with scent and flowers by means of the mantra phaṭ, / having given three claps upwards, having bound the ten directions with snaps of the fingers, / and having visualized a wall of fire with the stream of water with the syllable ram, he should perform the purification of the elements.
