The Madhyamika-karika testifies to the historicity to their author Nagarjuna, the great Buddhist philosopher, who extolled the path of Prajnaparamita. He wrote the Karika in order to expound the basic teaching of the Prajnaparamita-sutras. The recent archaeological discoveries at Amaravati corroborate to certain extent the broad facts about Nagarjuna\’s life on which his traditional biographies agree. He was born in a Brahmin family in Andhradesa at Vedali. Based on the Chinese author Tao-an (A.D.568) and Kumarjivas\’ account and his date for Buddha\’ nirvana and other material of a Japanese Scholar Hakaju concluded that Nagarjuna lived about 113-213 A.D. The fact being his friendship with a Satavahana King Gautamiputra Satakarni (130-150 A.D.) and his having spent the latter part of his career in the monastery built for him by this king at Bhramaragiri (Sriparvata). The Manjuasrimulakalpa and Tibetan sources contend that Nagarjuna had the Amaravati stupa renovated, enclosed and ornamented with the assistance of this King. Dhanyakataka and Sriparvata were the Centers of his activity. Rajatarangini of 11 th century treats him as a contemporary of Kanishka.
