empty nature of phenomena
Phenomena manifest in both pure and impure forms. Impure phenomena are the mundane experience in this world. Pure phenomena are when here is no dualistic Clinging. After becoming accustomed to this indivisible, unconfined, and undeluded state of dharmakaya, all phenomena appear without any self-nature.
The moment of recognizing mind essence is the instant as which impure experience, this habit of fixating upon all things as solid reality, disperses into basic space. What is left is pure experience, pure phenomena.
