Homage to Vajradakini

It is also traditional to begin a commentary with an homage to an enlightened being. Here the homage is to Vajradakini, also known as Vajrayogini, who is the focus of many Tantric practices. Dakinis are wise women who are guardians of Tantra. At several points in Tilopa's life he received and followed the advice of dakinis. Naropa also followed the advice of a dakini, who told him to seek out Tilopa as a teacher.
