Vajrasattva is the deity of purification and the ultimate embodiment of all the Buddhas.  The practice of this deity is one of the most important in Tibetan Buddhism as he represents the aspects of compassion and skillful means and the state of perfect wisdom.  Here, single form Vajrasattva is depicted in full lotus posture with the vajra of skill raised to his chest while its companion, the bell of wisdom, is inverted and silent at his hip.  Vajrasattva sits upon a white moon disc, and he wears the sambhogakaya ornaments.  His one hundred syllable purification mantra is renowned throughout all schools of Tibetan Buddhism.
