The text is accompanied here by an abridged version of its only commentary, originally written by the early Indian Bhikshu Vasitva, a monk who lived sometime in the middle or first half of the first millennium. This volume includes facing-page source text for the stanzas in both traditional and simplified scripts. Abridgement, notes, and translation by the American monk, Bhikshu Dharmamitra.
Acharya Nāgārjuna (Telugu: నాగార్జున) (c. 150 - 250 CE) was an Indian philosopher and the founder of the Madhyamaka school of Mahāyāna Buddhism.
His writings are the basis for the formation of the Madhyamaka school, which was transmitted to China under the name of the Three Treatise (Sanlun) School. He is credited with developing the philosophy of the Prajnaparamita sutras, and was closely associated with the Buddhist university of Nalanda. In the Jodo Shinshu branch of Buddhism, he is considered the First Patriarch.
