While all sentient beings and their worlds are relative and impermanent, the Buddha-mandala is free from conditioned existence, and the body according to this teaching is concretely held to be a Buddha-mandala. The essential point is that it is not something relative. The whole generation of the perishable world arises from the delusion of lack of pure presence, which is itself the creative energy of pristine awareness. This is the essential point that distinguishes this instruction.
— Padmasambhava, Guru Rinpoche
