Vajrakilaya is a wrathful form of Vajrasattva, the pure vajra nature of Enlightenment. In this imagery, the compassion of the Buddhas is expressed forcefully, to eradicate in a powerful way the entrenched ignorance and emotional afflictions which cause obstacles, interfering with auspicious circumstances and preventing the dawning of realisation. Thus, the symbol of compassion is the phurba or phurbu, the ritual dagger which stabs the obstacles and hostile forces of embodied ignorance, and transmits their consciousness to the Buddha fields.”
the wrathful heruka Vajrakilaya is the yidam deity who embodies the enlightened activity of all the buddhas and whose practice is famous for being the most powerful for removing obstacles, destroying the forces hostile to compassion and purifying the spiritual pollution so prevalent in this age. Vajrakilaya is one of the eight deities of Kagyé.
