Vairocanābhisaṃbodhi SūtraThe Vairocanābhisaṃbodhi Sūtra (Vairocana’s Awakening Sutra, 𑀯𑁃𑀭𑁄𑀘𑀦𑀸𑀪𑀺𑀲𑀁𑀩𑁄𑀥𑀺𑀲𑀽𑀢𑁆𑀭), also known as the Mahāvairocana Tantra (𑀫𑀳𑀸𑀯𑁃𑀭𑁄𑀘𑀦𑀢𑀦𑁆; ; also known as 大日經 Da Ri Jing) is an important Vajrayana Buddhist text composed before 674 CE. The Indian tantric master Buddhaguhya (fl. c.700 CE) classified the text as a caryātantra, and in Tibetan Buddhism it is still considered to be a member of the carya classification. In Japan where it is known as the Mahāvairocana Sūtra (Daibirushana jōbutsu jinpen kajikyō), it is one of two central texts in the Shingon school, along with the Vajrasekhara Sutra.
ZenZen (; ; ; ) is a school of Mahayana Buddhism that originated in China during the Tang dynasty, known as the Chan School (Chánzong 禪宗), and later developed into various sub-schools and branches. From China, Chán spread south to Vietnam and became Vietnamese Thiền, northeast to Korea to become Seon Buddhism, and east to Japan, becoming Japanese Zen. The term Zen is derived from the Japanese pronunciation of the Middle Chinese word 禪 (chán), an abbreviation of 禪那 (chánnà), which is a Chinese transliteration of the Sanskrit word ध्यान dhyāna ("meditation").
Shingon BuddhismShingon Buddhism is one of the major schools of Buddhism in Japan and one of the few surviving Vajrayana lineages in East Asia, originally spread from India to China through traveling monks such as Vajrabodhi and Amoghavajra. Known in Chinese as the Tangmi (唐密; the Esoteric School in the Tang dynasty of China), these esoteric teachings would later flourish in Japan under the auspices of a Buddhist monk named Kūkai (空海), who traveled to Tang China to acquire and request transmission of the esoteric teachings.
KūkaiKūkai (空海; 27 July 774 – 22 April 835), born Saeki no Mao (佐伯 眞魚), posthumously called Kōbō Daishi, was a Japanese Buddhist monk, calligrapher, and poet who founded the esoteric Shingon school of Buddhism. He travelled to China, where he studied Tangmi (Chinese Vajrayana Buddhism) under the monk Huiguo. Upon returning to Japan, he founded Shingon—the Japanese branch of Vajrayana Buddhism. With the blessing of several Emperors, Kūkai was able to preach Shingon teachings and found Shingon temples.
VairocanaVairocana (also Mahāvairocana, वैरोचन) is a cosmic buddha from Mahayana and Vajrayana Buddhism. Vairocana is often interpreted, in texts like the Avatamsaka Sutra, as the dharmakāya of the historical Gautama Buddha. In East Asian Buddhism (Chinese, Korean, Japanese and Vietnamese Buddhism), Vairocana is also seen as the embodiment of the Buddhist concept of śūnyatā. In the conception of the 5 Jinas of Mahayana and Vajrayana Buddhism, Vairocana is at the centre and is considered a Primordial Buddha.
Buddhist philosophyBuddhist philosophy is the ancient Indian philosophical system that developed within the religio-philosophical tradition of Buddhism. It comprises all the philosophical investigations and systems of rational inquiry that developed among various schools of Buddhism in ancient India following the parinirvāṇa of Gautama Buddha (c. 5th century BCE), as well as the further developments which followed the spread of Buddhism throughout Asia. Buddhism combines both philosophical reasoning and the practice of meditation.
VajrayanaVajrayāna (वज्रयान, "diamond vehicle""), also known as Mantrayāna, Guhyamantrayāna, Tantrayāna, Secret Mantra, Tantric Buddhism, and Esoteric Buddhism, is a Buddhist tradition of tantric practice that developed in the medieval Indian subcontinent and spread to Tibet, Nepal, other Himalayan states, East Asia, and Mongolia. Vajrayāna practices are connected to specific lineages in Buddhism, through the teachings of lineage holders. Others might generally refer to these texts as the Buddhist Tantras.
