In both Vedic and Buddhist Tantric traditions, empowerments or initiations into specific practices are indispensable.
Tantra is a deep ocean of wisdom and with its intricate symbolism, secret mantras and rituals it really cannot be learned from books or youtube.
There is no way one can really progress on the path of Tantra without proper guidance and empowerment.
Empowerment in this context translates to symbolic, oral or direct transmission of the essence of
Tantric practices and bestowal of the support, guidance, and protection of an authentic Lineage of Tantric Masters.
The empowerment enables a practitioner to execute the techniques correctly and also the ability to gain empirical knowledge.
Traditionally, Buddhist Yoga Tantra and Anuttarayoga Tantra empowerments are bestowed only to those
aspirants that have already taken the Principal Tantric and Four Great Boddhisatva vows.
These vows are to be taken in the presence and with the blessings of genuine spiritual authority (i.e. one’s Master).
