Tathāgatagarbha sūtras
The Sanskrit term tathāgatagarbha splits into two distinct roots that define the entire doctrine. The first root, tathāgata, refers to "the one thus gone" and points directly to Buddhahood itself. The second root, garbha, translates as "root," "embryo," or "womb." This linguistic combination creates a concept where every sentient being contains the potential for enlightenment within their own existence. Scholars note that while the terms tathagatagarbha and Buddha-nature do not share exactly identical meanings in all contexts, they became equated throughout Buddhist tradition. In the Angulimaliya Sūtra and the Mahāyāna Mahāparinirvāna Sūtra, these terms function as synonyms. The word describes an immortal, inherent transcendental essence residing in a concealed state within every single being.
Scholars associate some of the earliest Tathāgatagarbha sūtras with specific early Buddhist schools in ancient India. Brian Edward Brown dates the composition of the Śrīmālādevī Siñhanāda Sūtra to the 3rd century CE under the Andhra Ikshvaku dynasty. This text emerged as a product of the Mahāsāñghikas of the Andhra region. Sree Padma and Anthony Barber also link the earlier development of the Tathāgatagarbha Sūtra to the same group. They conclude that the Mahāsāñghikas of the Andhra region were responsible for the inception of this doctrine. Paul Williams writes that this collection appears less prominent in India compared to other traditions. It became increasingly popular and significant in Central Asian Buddhism and East Asian Buddhism instead. The concept originated in India but was a major influence on the development of East Asian Buddhism later.
The Mahāyāna Mahāparinirvāna Sūtra was considerably extended during its transmission to China. A similar and related sutra which synthesizes Buddha-nature with Yogacara is the Ghanavyūha Sūtra. Another major text, the Awakening of Faith, was originally composed in China rather than India. While the Ratnagotravibhāga has played a relatively small role in East Asian Buddhism, the Awakening of Faith holds centrality there. Chinese scholars created a list of types of Buddha-nature found within the Nirvana sutra due to its complex nature. This text speaks about Buddha-nature in so many different ways that it required systematic organization by later students. The tradition became linked with doctrines of Citta-mātra or Yogācāra in East Asian contexts. Vegetarianism gained support as all persons and creatures are compassionately viewed as possessing one and the same essential nature.
According to the Śrīmālādevī Siñhanāda Sūtra, the tathāgatagarbha is "not born, does not die, does not transfer, does not arise." It exists beyond the sphere of characteristics of the compounded state. Charles Muller comments that the tathagatagarbha expresses the already perfect aspect of the original nature of the mind. This nature remains clear and pure without arising or cessation. The doctrine states that sentient beings will have the qualities of a Buddha in the future, even if they lack them now. These qualities remain obscured from worldly vision by the screening effect of kleshas. Tenacious negative mental afflictions such as greed, hatred, delusion, and pride act as this screen. Once these negative mental states have been eliminated, the Buddhadhātu shines forth unimpededly. The tathāgatagarbha itself needs no cultivation, only uncovering or discovery since it is already present within each being.
Michael Radich provides a list of key Indian sutras associated with Tathāgatagarbha dating between 200 CE and the 3rd century CE. The Tathāgatagarbha Sūtra presents the concept as a virtual Buddha-homunculus seated majestically in the lotus position within the body of each being. This depiction is imagistically reminiscent of Mahāyāna descriptions of the Buddha sitting in his mother's womb prior to birth. The Śrīmālādevī Siñhanāda Sūtra describes the tathāgatagarbha as "the sphere of experience of the Tathāgatas." The Lañkāvatāra Sūtra from the 3rd century CE synthesizes tathāgatagarbha with the emptiness of prajñāpāramitā sutras. It identifies the luminous mind of the canon with the tathāgatagarbha while stating that it might be mistaken for a self which it is not. The text rigorously rejects nihilism and does not ultimately deny either self or world according to Thomas Cleary.
The Ratnagotravibhāga stands as the only Indian attempt to create a coherent philosophical model based on ideas found in the Tathāgatagarbha Sutras. Paul Williams comments on how impurity actually conceals the immanent true qualities of Buddha mind rather than being part of it. Despite East Asian Buddhism's propensity for these concepts, the treatise has played a relatively small role there due to the primacy of sutra study. Three other Indian Buddha-nature treatises exist preserved only in Chinese translations. These include the Dharmadhātvaviśešeśāstra attributed to Saramati and the Buddhagotraśāstra translated by Paramartha. The Awakening of Faith remains very important in East Asian Buddhism but is not studied in Tibetan Buddhism. The Ratnagotravibhāga especially draws on the Śrīmālādevī Siñhanāda Sūtra for its core arguments.
