Tantrayana / Vajrayana
Around the 6th. century AD, within the Mahayana tradition the tantras or tantric texts emerged. Based firmly on the Hinayana and Mahayana tradition, the actual philosophy differs only slightly from the Mahayana, but the practices can be quite different.
Prior to engaging in tantric practices, a proper understanding
of the Hinayana and Mahayana philosophy is considered essential. Only
then should one obtain initiation or permission from a qualified
tantric master to do a specific tantric practice.
Tantric practices are psychologically very profound techniques
to quickly achieve Buddhahood. This is considered important, not for
oneself, but because as a Buddha one has the best achievable qualities
to help others. The motivation is: 'the faster I can achieve
Buddhahood, the sooner I can be of maximum benefit to others'.
Depending on the class of tantra, extra vows may need to be
taken on top of the Refuge and Bodhisattva vows. Also, specific
commitments may be required like doing a specific retreat, daily
recitation of mantras or a daily meditation practice. (For more details
see the page on Tantra.)
In the 8th. century, the Mahayana and Tantrayana (or Vajrayana)
traditions of (North) Indian Buddhism were introduced into Tibet. In
fact, only in Tibet, Bhutan and Mongolia a virtually complete set of
tantric teachings was preserved.
The Tibetan tradition can also be found in the Himalayan range of
Ladakh (Northwest India), Sikkhim (Northeast India) and Nepal, and in
Mongolia (which is virtually identical to the Tibetan tradition). In
China and countries like Korea and Japan, remnants of Vajrayana can be
found.
The term Sutrayana is used within the Mahayana to indicate the non-tantric Mahayana teachings.
