The Treatise on the Great Virtue of Wisdom of Nagarjuna - Mahaprajnaparamitasastra - in five volumes — compiled by Etienne Lamotte
Prajnaparamita (Perfection of Wisdom) refers to this perfected way of seeing the nature of reality, as well as to a particular body of sutras and to the personification of the concept in the Bodhisattva known as the "Great Mother" (Tibetan: Yum Chenmo).
The bodhisattva Nagarjuna (Klu sgrub in Tibetan, 'converted by a dragon' or 'converting the dragons'; in Chinese Long chou 'dragon tree', Long mong 'unflinching dragon' or Long cheng 'victorious dragon') is one of the most enigmatic, yet also one of the richest, figures in Buddhism.
He lived in probably the second century of our era and played a role of primary importance in the formation of the Buddhism of the Greater Vehicle. Originally from the south, the country of Andhra, his influence extended as far as the north-west of India.
Dialectician and metaphysician, he is the founder of the Madhymaka or 'Middle-Way' school, which, while accepting the buddhology and the mysticism of the Greater Vehicle, submits the old texts of Buddhism to negative criticism and ends up with absolute emptiness (shunyata).
