The practice of Samayavajra is mainly for purifying degenerated commitments and vows.
Samayavajra is a Tantric Buddha who gas a green-colored body, three faces, one green, one black, and one white. He has six hands. The first two embrace his consort, who is similar in appearance. The other two right hands hold a vajra and a sword, and the other two left hands hold a bell and a lotus. Both the Father and the Mother are adorned with various jeweled ornaments.
The practice of Samayavajra can be found in the book Guide to Dakini Land.
