SvabhavaSvabhava (स्वभाव, svabhāva; सभाव, sabhāva; ; ) literally means "own-being" or "own-becoming". It is the intrinsic nature, essential nature or essence of beings. The concept and term svabhāva are frequently encountered in Hindu and Buddhist traditions such as Advaita Vedanta (e.g. in the Avadhūta Gītā), Mahāyāna Buddhism (e.g. in the Ratnagotravibhāga), Vaishnavism (e.g., the writings of Ramanuja) and Dzogchen (e.g. in the seventeen tantras). In the nondual Advaita Vedānta yoga text, Avadhūta Gītā, Brahman (in the Upanishadic denotation) is the svabhāva.
Buddha-natureIn Buddhist philosophy, Buddha-nature is the potential for any sentient beings to become a Buddha. It is a common English translation for several related Mahayana Buddhist terms, including tathata ("suchness") but most notably tathāgatagarbha and buddhadhātu. Tathāgatagarbha means "the womb" or "embryo" (garbha) of the "thus-gone" (tathāgata), or "containing a tathāgata", while buddhadhātu literally means "Buddha-realm" or "Buddha-substrate". Buddha-nature has a wide range of (sometimes conflicting) meanings in Indian and later East Asian and Tibetan Buddhist literature.
MadhyamakaMādhyamaka ("middle way" or "centrism"; ; Tibetan: དབུ་མ་པ ; dbu ma pa), otherwise known as Śūnyavāda ("the emptiness doctrine") and Niḥsvabhāvavāda ("the no svabhāva doctrine"), refers to a tradition of Buddhist philosophy and practice founded by the Indian Buddhist monk and philosopher Nāgārjuna (c. 150 – c. 250 CE). The foundational text of the Mādhyamaka tradition is Nāgārjuna's Mūlamadhyamakakārikā ("Root Verses on the Middle Way").
Two truths doctrineThe Buddhist doctrine of the two truths (Sanskrit: dvasatya, ) differentiates between two levels of satya (Sanskrit; Pali: sacca; word meaning "truth" or "reality") in the teaching of the Śākyamuni Buddha: the "conventional" or "provisional" (saṁvṛti) truth, and the "ultimate" (paramārtha) truth. The exact meaning varies between the various Buddhist schools and traditions. The best known interpretation is from the Madhyamaka school of Mahāyāna Buddhism, whose founder was the Indian Buddhist monk and philosopher Nāgārjuna.
ŚūnyatāŚūnyatā (ʃuːnˈjɑːtɑː ; śūnyatā; suññatā), translated most often as "emptiness", "vacuity", and sometimes "voidness", or "nothingness" is an Indian philosophical concept. Within Hinduism, Jainism, Buddhism, and other philosophical strands, the concept has multiple meanings depending on its doctrinal context. It is either an ontological feature of reality, a meditative state, or a phenomenological analysis of experience. In Theravāda Buddhism, suññatā often refers to the non-self (Pāli: anattā, Sanskrit: anātman) nature of the five aggregates of experience and the six sense spheres.
