Mahāyāna Buddhism in the context of "Yogachara"

Vajrayāna (Sanskrit: वज्रयान, lit. 'Diamond Vehicle or Thunderbolt Vehicle'), otherwise known as Mantrayāna ("Mantra Vehicle"), Guhyamantrayāna ("Secret Mantra Vehicle"), Tantrayāna ("Tantra Vehicle"), Indo-Tibetan Buddhism, Tantric Buddhism, and Esoteric Buddhism, is a Mahāyāna Buddhist tradition that emphasizes esoteric practices and rituals aimed at rapid spiritual awakening. Emerging between the 5th and 7th centuries CE in medieval India, Vajrayāna Buddhism incorporates a range of techniques, including the use of mantras (sacred sounds), dhāraṇīs (mnemonic codes), mudrās (symbolic hand gestures), mandalās (spiritual diagrams), and the visualization of deities and Buddhas. These practices are designed to transform ordinary experiences into spiritual paths toward enlightenment and liberation, often by engaging with aspects of desire and aversion in a ritualized context.

A distinctive feature of Vajrayāna Buddhism is its emphasis on esoteric transmission, where teachings are passed directly from teacher (guru or vajrācārya) to student through initiation ceremonies. Tradition asserts that these teachings have been passed down through an unbroken lineage going back to the historical Buddha (c. the 5th century BCE), sometimes via other Buddhas or bodhisattvas (e.g., Vajrapani). This lineage-based transmission ensures the preservation of the purity and effectiveness of the teachings. Practitioners often engage in deity yoga, a meditative practice where one visualizes oneself as a deity embodying enlightened qualities to transform one's perception of reality. The tradition also acknowledges the role of feminine energy, venerating female Buddhas and ḍākiṇīs (spiritual beings), and sometimes incorporates practices that challenge conventional norms to transcend dualistic thinking.

Manjushri (Sanskrit: मञ्जुश्री, romanized: Mañjuśrī) is a bodhisattva who represents prajñā (transcendent wisdom) of the Buddhas in Mahāyāna Buddhism. The name "Mañjuśrī" is a combination of Sanskrit word "mañju" and an honorific "śrī"; it can be literally translated as "Beautiful One with Glory" or "Beautiful One with Auspiciousness". Mañjuśrī is also known by the fuller name of Mañjuśrīkumārabhūta (मञ्जुश्रीकुमारभूत), literally "Mañjuśrī, Still a Youth" or, less literally, "Prince Mañjuśrī". Another name of Mañjuśrī is Mañjughoṣa.

Seon or Sŏn Buddhism (Korean: 선; Hanja: 禪; Korean pronunciation: [sʌn]) is the Korean name for Chan Buddhism, a branch of Mahāyāna Buddhism commonly known in English as Zen Buddhism. Seon is the Sino-Korean pronunciation of Chan, (Chinese: 禪; pinyin: chán) an abbreviation of 禪那 (chánnà), which is a Chinese transliteration of the Sanskrit word of dhyāna ("meditation"). Seon Buddhism, represented chiefly by the Jogye and Taego orders, is the most common type of Buddhism found in Korea.

A main characteristic of Seon Buddhism is the use of the method of meditation, Ganhwa Seon. A Korean monk, Jinul accepted partially a meditative method of Chan Buddhism in 1205. In Chan Buddhism, hwadu (화두; 話頭) is a delivery of realising a natural state of the Awakening. Jinul addressed a doctrine of Sagyo Yiepseon (사교입선; 捨敎入禪) that monks should live an inborn life after learning and forgetting all creeds and theories. Within the doctrine of Jinul, hwadu is the witnessing of truthful meaning in everyday life.

Buddhism in Cambodia or Khmer Buddhism (Khmer: ព្រះពុទ្ធសាសនានៅកម្ពុជា, UNGEGN: Preăh Pŭtthôsasânéa noŭ Kâmpŭchéa) has existed since at least the 5th century. In its earliest form it was a type of Mahāyāna Buddhism. Today, the predominant form of Buddhism in Cambodia is Theravada Buddhism. It is enshrined in the Cambodian constitution as the official religion of the country. Theravada Buddhism has been the Cambodian state religion since the 13th century (except during the Khmer Rouge period). As of 2019 it was estimated that 97.1 percent of the population are Buddhists.

The history of Buddhism in Cambodia spans a number of successive kingdoms and empires. Buddhism entered Cambodia via two different streams. The earliest forms of Buddhism, along with Hindu influences, entered the Kingdom of Funan with Hindu merchants. In later history, a second stream of Buddhism entered Khmer culture during the Angkor empire when Cambodia absorbed the various Buddhist traditions of the Mon kingdoms of Dvaravati and Haripunchai.

Devotion, a central practice in Buddhism, refers to commitment to religious observances or to an object or person, and may be translated with Sanskrit or Pāli terms like saddhā, gārava or pūjā. Central to Buddhist devotion is the practice of Buddhānussati, the recollection of the inspiring qualities of the Buddha. Although buddhānussati was an important aspect of practice since Buddhism's early period, its importance was amplified with the arising of Mahāyāna Buddhism. Specifically, with Pure Land Buddhism, many forms of devotion were developed to recollect and connect with the celestial Buddhas, especially Amitābha.

Most Buddhists use ritual in pursuit of their spiritual aspirations. Common devotional practices are receiving a blessing, making merit, making a resolution, prostrating, making offerings, chanting, confession and repentance, and pilgrimage. Moreover, many types of visualizations, recollections and mantras are used in Buddhist meditation in different traditions to devote oneself to a Buddha, bodhisattva, or a teacher / guru. The often politically motivated practice of self-immolation is a less common aspect of devotion in some Buddhist communities.

Buddhism in Southeast Asia includes a variety of traditions of Buddhism including two main traditions: Mahāyāna Buddhism and Theravāda Buddhism. Historically, Mahāyāna had a prominent position in the region, but in modern times, most countries follow the Theravāda tradition. Southeast Asian countries with a Theravāda Buddhist majority are Thailand, Cambodia, Laos, Myanmar, all of them mainland countries.

Vietnam continues to have a Mahāyān majority due to Chinese influence. Indonesia was Theravāda Buddhist since the time of the Sailendra and Srivijaya empires, but Mahāyāna Buddhism in Indonesia is now largely practiced by the Chinese diaspora, as in Singapore and Malaysia. Mahāyāna Buddhism is the predominant religion of Chinese communities in Singapore, Malaysia, Brunei, and Indonesia.
