Samantabhadra

The editor says Samantabhadra, earlier than Pūjyapāda, wrote a Siddhānta Rasāyana Kalpa of 18,000 verses, now largely eaten by insects, using Jain technical terms and codes: Ratnatrayauṣadha names a rasāyana of mercury, sulphur and pāṣāṇa that removes the three doṣas as the three jewels remove the three faults, and quantities are coded by the emblems of the tīrthaṅkaras. He quotes Samantabhadra's verse on the virtues of rasasindūra and describes the lexicons, such as Amṛtanandi's, needed to decode such terms.
