THE GREAT PRAJNA PARAMITA SUTRA
The most extensive Buddhist canon ever translated into English, now freely available for every seeker of wisdom.
The Great Prajna Paramita Sutra is the largest canon in Buddhism, spanning approximately five million words across 600 fascicles. Originally translated from Sanskrit into Chinese by the monk Xuanzang between 660 and 663 CE, this monumental text has now been rendered into English in its complete, unabridged form for the first time.
Prajna means wisdom, not merely intellectual knowledge, but the deep understanding of life, existence, and all phenomena. Paramita means ferrying across the ocean of suffering to reach the shore of liberation and happiness. Together, prajna paramita represents the highest wisdom, described in this sutra as the mother of all Buddhas.
This sutra encompasses the Diamond Sutra and the Heart Sutra, among many other teachings, delivered by the Buddha across 16 assemblies over 22 years. It guides bodhisattvas through the complete path of cultivation, from the practice of the six paramitas to the attainment of perfect and universal enlightenment, offering a timeless roadmap for all who aspire toward Buddhahood.
