Tathāgatagarbha
Summary
The article examines the Mahayana and Yogacara Buddhist concept of Tathagatagarbha, a term used to denote a particular aspect of ultimate reality. The author argues that Tathagatagarbha refers to the totality of worldly beings who possess a pure mind with no beginning, yet remain obscured by beginningless mental impurities. This concept indicates that every being is potentially a Tathagata and essentially one and the same, though commonly dichotomized as pure and impure. The article discusses evidence and sources, including the *Lankavatara Sutra* and the *Ratnagotravibhaga*. The *Lankavatara Sutra* uses similes, such as a king remaining in the womb or a lotus covered in dirt, to illustrate that Tathagatagarbha exists in all beings but is hidden by impurities. The *Ratnagotravibhaga* categorizes beings into those destined, undestined, or destined for wrong views, all of whom possess Tathagatagarbha. The author also explores the relationship between Tathagatagarbha and other concepts like Tathata (Thatness), Cittamatra (Mind-only), and Alayavijnana (storehouse consciousness). Tathagatagarbha is equated with pure and impure Tathata, and while it is allied with Cittamatra and Alayavijnana, it uniquely emphasizes the inherent presence of the Tathagata's essence in all beings. The article further compares Tathagatagarbha to the Vedantic concept of Brahman, noting that while both are non-dual and pure, Tathagatagarbha is not individualized. The author concludes that Tathagatagarbha represents the combination of samsara and nirvana, embodying both the mundane and the supra-mundane. It epitomizes the law of dependent origination and establishes that samsara has only notional existence. Ultimately, the eternal aspect of Tathagatagarbha is identical with Sanyata (emptiness), Tathata, and Dharmakaya, though Yogacara texts focus more on its impure aspect and purification.

Conclusion
This article demonstrates that Tathāgatagarbha functions as a pivotal Mahāyāna concept denoting the inherent potential for Buddhahood within all sentient beings. It synthesizes the ultimate, absolute truth (such as *Bhitatathatā*, *Śūnyatā*, and *Dharmakāya*) with the relative, phenomenal world of *Saṃsāra*. By integrating the pure essence of *Dharmakāya* with the foundational, yet potentially impure, nature of *Ālayavijñāna*, Tathāgatagarbha bridges the gap between the mundane and the transcendent. Its primary significance lies in its pedagogical utility; it serves as an expedient (*upāya*) to guide unenlightened beings toward the realization of the highest truth without frightening them away from the absolute. Ultimately, the concept affirms the non-dual, eternal, and pure essence of all existence.
