Buddha Amideva is realized to be none other than the true thusness of the body and mind of all sentient beings, the essentially pure, perfectly bright, wisdom body of equanimity that is always-already possessed. That which is referred to as the ‘eight-petaled heart lotus of sentient beings’ is none other than the three point mandala of Amideva.
Though submerged in ignorance and muck, this mind of enlightenment is neither defiled nor hidden. Though revealed by the Buddha’s light of initial awakening, it is neither arisen nor made manifest. In the past, present, and future, it is unchanging. The manifold virtues are thusly steadfast.
