One of the most interesting notions found in the early
tathāgatagarbha literature is the idea that
nirvāṇa should be understood as nonorigination (
anutpāda). This idea is explicitly formulated in two texts, the
Ratnagotravibhāga, the only
śāstra extant in Sanskrit which is completely devoted to the
tathāgatagarbha and Buddha-nature teachings, and the
Jñānālokālaṅkārasūtra, the
sūtra upon which the
Ratnagotravibhāga bases its exposition of nonorigination. The
Jñānālokālaṅkārasūtra itself does not speak of the
tathāgatagarbha or Buddha-nature doctrines, but the
Ratnagotravibhāga takes the
Jñānālokālaṅkārasūtra explanation of nonorigination and links it to the view of
nirvāṇa found in two of the important early
sūtras that do speak of the
tathāgatagarbha, the
Anūnatvāpūrṇatvanirdeśa and the
Śrīmālādevīsūtra. This interpretation of
nirvāṇa in terms of nonorigination is of considerable importance in understanding the early
tathāgatagarbha teaching, for it clarifies certain notions frequently associated with the
tathāgatagarbha like the "natural purity of mind" (
cittaprakṛtiviśuddhi)—notions which have been hotly debated ever since the doctrine's inception. It may also tell us something about the conceptual issues which divided the schools of early Buddhism and so hold clues for understanding the origin of Mahāyāna Buddhism. (Grosnick, "Nonorigination and
Nirvāṇa," 33)
