kardamaṃ ca kumāryāśca rasena kṛtagolakam
dhamanāt patate sattvaṃ mukhe taddhārayennaraḥ
ṣaṇmāsena prayogeṇa hy ajarāmaratāṃ vrajet //

An alchemical pellet made with the slime and juice of kumārī; / from blowing, the metallic essence falls; a man should hold that in his mouth: / by a six-month practice, he surely attains freedom from old age and death.
