One must then chant the mantra of six syllables [oṁ viṣṇave namaḥ]. One should place the syllable om on his heart, the syllable vi on the top of his head, the syllable sa between his eyebrows, the syllable na on his tuft of hair [śikhā], and the syllable ve between his eyes. The chanter of the mantra should then place the syllable na on all the joints of his body and meditate on the syllable ma as being a weapon. He should thus become the perfect personification of the mantra. Thereafter, adding visarga to the final syllable ma he should chant the mantra maḥ astrāya phaṭ in all directions, beginning from the east. In this way, all directions will be bound by the protective armor of the mantra.
