sūto dvitricatuḥpañcaguṇastīkṣṇena jāritaḥ /
uttarottaratastasya guṇaḥ keneha varṇyate /
{mercury:: jāraṇa:: with kāntaloha}
kāntajīrṇarasaś caivaṃ guṇaiḥ koṭiguṇaṃ bhavet //

When mercury has digested two, three, four, or five times the amount of cast iron, / by whom in this world can its progressively increasing virtue be described?
{Mercury: digestion with lodestone}
And thus mercury with digested lodestone becomes ten-million-fold in its virtues.
