Be Comfortable with Illusory Manifestations

Correcting concepts to align them with truth, aka purifying concepts, is the pillar of Mahayana.

In Vajrayana's sadhana meditation, appearances, without center or limit, arise like moon discs reflected in water. This relationship with appearances is characterized as the blissful path of openness and awareness.

Everything that arises from the sky-space of emptiness has the characteristic of sky-space but sky-space is without characteristics. All is equal.
