'At this stage the meditator will acquire some power of supernormal cognition and will receive prophetic directions from his yidam and dakini. ... If the meditator has failed to acquire the spiritual power capable of producing both beneficial and harmful effects, has failed to gain supernormal cognition, and has also failed to receive any prophetic directions from the dakinis despite the fact that he has realized the great level of one flavor, then this condition might well be the consequence of his having violated the sacred bond or having been affected by a close associate who has abandoned his faith.'
(Mahamudra: the Moonlight, p 397-398)
'"Prophetic directions from the dakinis" refers to the protective role of the dakinis. Regarded as the custodians of the secret Supreme Yoga, the dakinis have been looked upon by Buddhist mystics as the protectors from forces of destruction and unscrupulous profaning.'
