Nalanda mahaviharaNalanda (ISO, naːlən̪d̪aː) was a renowned mahavihara (Buddhist monastic university) in ancient Magadha (modern-day Bihar), eastern India. Considered by historians to be the world's first residential university and among the greatest centers of learning in the ancient world, it was located near the city of Rajagriha (now Rajgir) and about southeast of Pataliputra (now Patna). Operating from 427 until 1197 CE, Nalanda played a vital role in promoting the patronage of arts and academics during the 5th and 6th century CE, a period that has since been described as the "Golden Age of India" by scholars.
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.
TantraTantra (ˈtæntrə; तन्त्र) refers to an esoteric yogic tradition that developed on the Indian subcontinent from the middle of the 1st millennium CE onwards in both Hinduism and Buddhism. The term tantra, in the Indian traditions, also means any systematic broadly applicable "text, theory, system, method, instrument, technique or practice". A key feature of these traditions is the use of mantras, and thus they are commonly referred to as Mantramārga ("Path of Mantra") in Hinduism or Mantrayāna ("Mantra Vehicle") and Guhyamantra ("Secret Mantra") in Buddhism.
Tibetan BuddhismTibetan Buddhism is a form of Buddhism practiced in Tibet and Mongolia. It also has a sizable number of adherents in the areas surrounding the Himalayas, including the Indian regions of Ladakh, Sikkim, and Arunachal Pradesh, as well as Bhutan and Nepal. Smaller groups of practitioners can be found in Central Asia, Xinjiang, Inner Mongolia, and some regions of Russia, such as Tuva, Buryatia, and Kalmykia. Tibetan Buddhism evolved as a form of Mahāyāna Buddhism stemming from the latest stages of Indian Buddhism (which included many Vajrayāna elements).
