This rupa of Padmasambhava was carved by one of his chief disciples, Ngungma. The statue changes color with the waxing and waning of the moon, from red to white. Carved out of soapstone very much in the likeness of Padmasambhava, it is said to contain relics of Padmasambhava inside it.

If you come into contact with this particular rupa, it brings what is called, "The power of Hayagriva." Hayagriva is one of the eight aspects of the mahayoga of the Nyingma tantra. This particular yidam, Hayagriva, has a horse's head. When this horse neighs, the neigh is said to wake you up.
