The Samdhinirmochana Sutra (Skt. Saṃdhinirmocana sūtra; Tib. དགོངས་པ་ངེས་འགྲེལ་, Wyl. dgongs pa nges 'grel; Eng. Sutra of Unraveling the Intent) is a famous mahayana sutra in 10 chapters that is particularly associated with the Yogachara school. It is one of the ten sutras that teach the sugatagarbha and classified as being part of the third turning of the wheel of dharma.
The Samdhinirmochana Sutra has played a major role in Tibetan hermeneutical debates. For centuries, it has been considered a central scripture referred to extensively in the writings of Tibet’s great luminaries, such as Jé Tsongkhapa or Jamgön Mipham Gyatso.
- In the first chapter, the bodhisattva Vidhivatpariprcchaka questions the bodhisattva Gambhirarthasamdhinirmocana on the inexpressible and nondual ultimate.
- In the second chapter, the bodhisattva Dharmodgata questions the Buddha on the ultimate beyond speculation.
- In the third chapter, the bodhisattva Suvishuddhamati questions the Buddha on the ultimate that is beyond being distinct or indistinct from conditioned phenomena.
- In the fourth chapter, Subhuti questions the Buddha on the ultimate that is of a single nature within all phenomena.
- In the fifth chapter, the bodhisattva Vishalamati questions the Buddha on the secrets of mind (citta), thought (manas), and cognition or consciousness (vijñāna).
- In the sixth chapter, the bodhisattva Gunakara questions the Buddha on the three defining characteristics or three natures (lakṣaṇa) of phenomena.
- In the seventh chapter, the bodhisattva Paramarthasamudgata questions the Buddha on the three kinds of essencelessness as well as on the Buddha’s three turnings of the Dharma wheel.
- In the eighth chapter, the bodhisattva Maitreya questions the Buddha on the practice of shamatha and vipashyana.
- In the ninth chapter, the bodhisattva Avalokiteshvara questions the Buddha on the stages of the bodhisattva path and the Single Vehicle (ekayāna).
- In the tenth chapter, the bodhisattva Mañjushri questions the Buddha on the kayas and activity of the buddhas.
From a broader perspective, it is possible to consider that the teaching imparted in this sutra is structured in terms of ground, path, and fruition.
- The first four chapters on the five characteristics of the ultimate as defined in the Prajñaparamita sutras represent a teaching on the ground, namely, true reality (tathatā) as it is;
- chapters 5–9, a teaching on the path in terms of practices and stages to attain awakening; and
- chapter 10, a teaching on the result through the doctrine of the tathagatas’ bodies and activity to awaken beings.
All major Tibetan traditions consider chapter 3, focusing on the relation between the two truths, and chapter 8, focusing on meditative practice, to be authoritative. These are among the scriptures most quoted on their respective topics by Tibetan authors regardless of lineage.
Only fragments of the original Sanskrit text are extant; the only complete extant versions of the Samdhinirmochana Sutra are Chinese and Tibetan translations produced from Sanskrit manuscripts.
This sutra was first translated into Chinese by:
- Guṇabhadra around 440,
- Bodhiruci in 514,
- Paramartha in 557, and
- Xuanzang in 647.
It was translated into Tibetan towards the end of the eighth century by Chokro Lüi Gyaltsen and can be found in the Tibetan Kangyur, General Sutra Section, Toh 106.
The fact that Xuanzang's Chinese version and Chokro Lüi Gyaltsen's Tibetan version are so similar might allow us to believe that they are both the translation of the same Sanskrit version.
