Siddha Nāgārjuna

The editor says Siddha Nāgārjuna, Pūjyapāda's sister's son, wrote the Nāgārjuna Kalpa, the Nāgārjuna Kakṣapuṭa and other works, and tells the story of his gold-making gem-pill, the Vajrakhecaraghuṭikā: he pledged his eyes to a king, lost the three gems in a river and was blinded, a courtesan found them in a fish, turned iron into gold with them and founded the Nāgārjunasatra almshouse, and Nāgārjuna recovered the gems and his sight. The editor offers the story as showing the power of Ayurvedic medicine.
