"In the Sanskrit name of The Diamond Sutra, vajrachedika, or 'diamond,' refers to the unbreakable foundation of self-nature inherent in the human mind; prajñā to the light of self-nature that ceaselessly surges forth from that foundation; and pāramitā to the recovery of the adamantine self-nature and actions based on that self-nature, by using its light to hone wisdom for the practice of a life without delusion." -- Back of book.
