For three days, one should drink one kuḍava measure [of the preparation] to remove the defects of salt, using Viḍaṅga, Vacā, and Kuṣṭha mixed with Ketakī fluid. (5) Drinking this for three days is the supreme destroyer of acid defects. [Use] Śyāmā, Vahni, Viḍaṅgas, Triphalā, (6) Rock salt, Deodara, and Mustā in equal parts. [Taking] one karṣa measure of this ghee-electuary destroys all defects. (7) Having purified the body in this way, one should worship the deity and the guru, then the maiden, and the cycle of yoginīs; then one should perform the elixir ritual. (8)
