Luminous mind in the context of "Mahasanghika"

Buddhist meditation is the practice of meditation in Buddhism. The closest words for meditation in the classical languages of Buddhism are bhāvanā ("mental development") and jhāna/dhyāna (a state of meditative absorption resulting in a calm and luminous mind).

Buddhists pursue meditation as part of the path toward liberation from defilements (kleshas) and clinging and craving (upādāna), also called awakening, which results in the attainment of nirvana. The Indian Buddhist schools relied on numerous meditation techniques to attain meditative absorption, some of which remain influential in certain modern schools of Buddhism. Classic Buddhist meditations include anapanasati (mindfulness of breathing), asubha bhavana ("reflections on repulsiveness"); reflection on pratityasamutpada (dependent origination); anussati (recollections, including anapanasati), the four foundations of mindfulness, and the divine abodes (including loving-kindness and compassion). These techniques aim to develop various qualities including equanimity, sati (mindfulness), samadhi (unification of mind) c.q. samatha (tranquility) and vipassanā (insight); and are also said to lead to abhijñā (supramundane powers). These meditation techniques are preceded by and combined with practices which aid this development, such as moral restraint and right effort to develop wholesome states of mind.

The Laṅkāvatāra Sūtra (Sanskrit: लङ्कावतारसूत्रम्, "Discourse of the Descent into Laṅkā", Standard Tibetan: ལང་ཀར་བཤེགས་པའི་མདོ་, Chinese: 入楞伽經) is a prominent Mahayana Buddhist sūtra. It is also titled Laṅkāvatāraratnasūtram (The Jewel Sutra of the Entry into Laṅkā, Gunabhadra's Chinese title: 楞伽阿跋多羅寶經 léngqié ābáduōluó bǎojīng) and Saddharmalaṅkāvatārasūtra (The Sutra on the Descent of the True Dharma into Laṅkā). A subtitle to the sutra found in some sources is "the heart of the words of all the Buddhas" (一切佛語心 yiqiefo yuxin, Sanskrit: sarvabuddhapravacanahṛdaya).

The Laṅkāvatāra recounts a teaching primarily between Gautama Buddha and a bodhisattva named Mahāmati ("Great Wisdom"). The sūtra is set in mythical Laṅkā, ruled by Rāvaṇa, the king of the rākṣasas. The Laṅkāvatāra discusses numerous Mahayana topics, such as Yogācāra philosophy of mind-only (cittamātra) and the three natures, the ālayavijñāna (store-house consciousness), the inner "disposition" (gotra), the buddha-nature, the luminous mind (prabhāsvaracitta), emptiness (śūnyatā) and vegetarianism.

In Buddhist philosophy and soteriology, Buddha-nature (Chinese: fóxìng 佛性, Japanese: busshō 佛性, Vietnamese: Phật tính, Sanskrit: buddhatā, buddha-svabhāva or tathāgatagarbha तथागतगर्भ) is the innate potential for all sentient beings to become a Buddha or the fact that all sentient beings already have a pure Buddha-essence within themselves. "Buddha-nature" is the common English translation for several related Mahāyāna Buddhist terms, most notably tathāgatagarbha (तथागतगर्भ) and buddhadhātu, but also sugatagarbha, and buddhagarbha. Tathāgatagarbha can mean "the womb" or "embryo" (garbha) of the "thus-gone one" (tathāgata), and can also mean "containing a tathāgata". Buddhadhātu can mean "buddha-element", "buddha-realm", or "buddha-substrate".

Buddha-nature has a wide range of (sometimes conflicting) meanings in Indian Buddhism and later in East Asian and Tibetan Buddhist literature. Broadly speaking, it refers to the belief that the luminous mind, "the natural and true state of the mind", which is pure (visuddhi) mind undefiled by afflictions, is inherently present in every sentient being, and is eternal and unchanging. It will shine forth when it is cleansed of the defilements, that is, when the nature of mind is recognized for what it is.
