Mahayana sutras in the context of "Pure Land Buddhism"

Amitābha (Sanskrit pronunciation: [ɐmɪˈtaːbʱɐ], "Measureless" or "Limitless" Light), also known as Amituofo in Chinese, Amida Butsu in Japanese, Amita-bul in Korean, A Di Đà Phật in Vietnamese, and Öpakmé in Tibetan, is one of the main Buddhas of Mahayana Buddhism and the most widely venerated Buddhist figure in East Asian Buddhism. Amitābha is also known by the name Amitāyus ("Measureless Life").

Amitābha is the main figure in two influential Indian Buddhist Mahayana Scriptures: the Sutra of Measureless Life and the Amitābha Sūtra. According to the Sutra of Measureless Life, Amitābha established a pure land of perfect peace and happiness, called Sukhāvatī ("Blissful"), where beings who mindfully remember him with faith may be reborn and then quickly attain enlightenment. The pure land is the result of a set of vows Amitābha made long ago. As his name means Limitless Light, Amitābha's light is said to radiate throughout the cosmos and shine on all beings. Because of this, Amitābha is often depicted radiating light, a symbol for his wisdom. As per the name Amitāyus, this Buddha is also associated with infinite life, since his lifespan is said to be immeasurable. Amitābha's measureless life is seen as being related to his infinite compassion.

Prajñā (प्रज्ञा) or paññā (𑀧𑀜𑁆𑀜𑀸) is a Buddhist term often translated as "wisdom", "transcendental wisdom", "insight", "intelligence", or "understanding". It is described in Buddhist texts as the understanding of the true nature of phenomena. In the context of Buddhist meditation, it is the ability to understand the three characteristics of all things: anicca ("impermanence"), dukkha ("dissatisfaction" or "suffering"), and anattā ("non-self" or "egolessness"). Mahāyāna texts describe it as the understanding of śūnyatā ("emptiness"). It is part of the Threefold Training in Buddhism, and is one of the ten pāramīs of Theravāda Buddhism and one of the six Mahāyāna pāramitās.

East Asian Buddhism or East Asian Mahayana is a collective term for the schools of Mahāyāna Buddhism which developed across East Asia and which rely on the Chinese Buddhist canon. These include the various forms of Chinese, Japanese, Korean, and Vietnamese Buddhism. East Asian Buddhists constitute the numerically largest body of Buddhist traditions in the world, numbering over half of the world's Buddhists.

East Asian forms of Buddhism all derive from the sinicized Buddhist schools which developed during the Han dynasty and the Song dynasty, and therefore are influenced by Chinese culture and philosophy. The spread of Buddhism to East Asia was aided by the trade networks of the Silk Road and the missionary work of generations of Indian and Asian Buddhists. Some of the most influential East Asian traditions include Chan (Zen), Nichiren Buddhism, Pure Land, Huayan, Tiantai, and Chinese Esoteric Buddhism. These schools developed new, uniquely East Asian interpretations of Buddhist texts and focused on the study of Mahayana sutras. According to Paul Williams, this emphasis on the study of the sutras contrasts with the Tibetan Buddhist attitude which sees the sutras as too difficult unless approached through the study of philosophical treatises (shastras).

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.

The Aṣṭasāhasrikā Prajñāpāramitā Sūtra (Sanskrit: अष्टसाहस्रिका प्रज्ञापारमिता सूत्र; English: The Perfection of Wisdom in Eight Thousand [Lines]) is a Mahāyāna Buddhist sūtra in the category of Prajñāpāramitā sūtra literature. The sūtra's manuscript witnesses date to at least c. 184 BCE – c. 46 BCE, making it among the oldest Buddhist manuscripts in existence. The sūtra forms the basis for the expansion and development of the Prajñāpāramitā sūtra literature. In terms of its influence in the development of Buddhist philosophical thought, P.L. Vaidya writes that "all Buddhist writers from Nāgārjuna, Āryadeva, Maitreyanātha, Asaṅga, Vasubandhu, Dignāga, down to Haribhadra concentrated their energies in interpreting Aṣṭasāhasrikā only," making it of great significance in the development of Madhyāmaka and Yogācāra thought.

The sūtra deals with a number of topics, but is primarily concerned with the conduct of a bodhisattva, the realisation and attainment of the Perfection of Wisdom as one of the Six Perfections, the realisation of thusness (tathātā), the attainment of irreversibility on the path to buddhahood (avaivartika), non-conceptualisation and abandonment of views, as well as the worldly and spiritual benefit of worshipping the sūtra.

The Amitāyus Sutra (Sanskrit), simplified Chinese: 佛说无量寿经; traditional Chinese: 佛說無量壽經; pinyin: Fóshuō Wúliàngshòu Jīng; Sutra of Immeasurable Life Spoken by Buddha; Vietnamese: Phật Thuyết Vô Lượng Thọ Kinh; Japanese: Bussetsu Muryōju Kyō (Taisho Tripitaka no. 360), also known as the Longer Sukhāvatīvyūha Sūtra, is one of the two Indian Mahayana sutras which describe the pure land of Amitābha (also known as Amitāyus, "Measureless Life"). Together with the Sukhāvatīvyūha Sūtra, this text is highly influential in East Asian Buddhism. It is one of the three central scriptures of East Asian Pure Land Buddhism, and is widely revered and chanted by Pure Land Buddhists throughout Asia.

The title is often translated in English as either the Sutra [on the Buddha] of Immeasurable Life, or simply the Immeasurable Life Sutra.

The Amitābha Sūtra (Ch.: 阿彌陀經, pinyin: Āmítuó Jīng, or 佛說阿彌陀經, Fóshuō Āmítuó Jīng; Jp.: Amida Kyō, Vi.: A Di Đà Kinh), also known as the [Shorter] Sukhāvatīvyūha Sūtra (Sanskrit, The Array of "the Blissful Land", or The Arrangement of Sukhāvatī) is one of the two Indian Mahayana sutras that describe Sukhāvatī, the pure land of Amitābha. The text was translated into Chinese in 402 by Kumārajīva (Taishō Tripiṭaka no. 366) and it is also known in Chinese as the "Small Sutra" (Xiaojing).

The Amitābha Sūtra is highly influential in East Asian Buddhism, including China, Korea, Japan, and Vietnam since it is considered one of the "Three Pure Land" sutras which are the key scriptures in Pure Land Buddhism.

Luminous mind (Skt: prabhāsvara-citta or ābhāsvara-citta, Pali: pabhassara citta; Tib: འོད་གསལ་གྱི་སེམས་ ’od gsal gyi sems; Ch: 光明心 guangmingxin; Jpn: 光明心 kōmyōshin) is a Buddhist term that appears only rarely in the Pali Canon, but is common in the Mahayana sūtras and central to the Buddhist tantras. It is variously translated as "brightly shining mind" or "mind of clear light", while the related term luminosity (Skt. prabhāsvaratā; Tib. འོད་གསལ་བ་ ’od gsal ba; Ch. guāng míng; Jpn. kōmyō; Kor. kwangmyōng) is also translated as "clear light" or "luminosity" in Tibetan Buddhist contexts or "purity" in East Asian contexts.

The Theravada school identifies the "luminous mind" with the bhavanga, a concept first proposed in the Theravāda Abhidhamma. The later schools of the Mahayana identify it with bodhicitta and tathagatagarbha. The luminosity of mind is of central importance in the philosophy and practice of the Buddhist tantras, Mahamudra, and Dzogchen.
