"The mantrin should extract the mantra consisting of three seed-syllables: the vāgbhava, the consort of Śambhu, and Ramā, / which accomplishes the fruit of the three goals of life. / One should perform all the placements, worship, and the rest as before." (41) But as for the placement on the six limbs, there is a particularity: / "Aiṃ hrāṃ, homage to the two thumbs," and so forth.
