“We need the visualization of Vajrasattva as a support for realizing our buddha nature because we are so habituated to our concepts. We continually relate to the world as if we were truly-existing subjects who perceive truly-existing objects. Once we move beyond duality and merge with Vajrasattva in the ultimate nature, we will no longer do this.
“…visualize Buddha Vajrasattva one forearm span above your head, seated on a lotus with a thousand petals. The luminous stalk of the lotus comes down through the top of your head. Your crown chakra is open and surrounded by a halo of light. A white moon disk covers the pollen bed of the lotus, upon which Vajrasattva sits in the vajra posture. His body is not solid; it is made of the light of wisdom and compassion….
…As the embodiment of compassion and wisdom, he is none other than Guru Padmasambava and the heart of your root teacher and all the lineage masters, but he appears in the sambhogakaya form. In his right hand he holds a vajra vertically at the level of his heart center. His left hand is leaning on his hip and holding a bell.”
