Through practicing the sense of the Three Wheels of Dharma, one accords with the purification of the coarse, subtle, and extremely subtle defilements of the Buddha Nature, which is like a wish-fulfilling jewel.
The First Wheel (teachings on cause and effect) is preliminary for, and follows in accord with, meditation on the profound Mahayana that is definitive in meaning.
The Second Wheel (on the absence of characteristics) also accords with the practice of the exceptional meditative stabilization of resting in equipoise on the profound meaning.
The Third Wheel (on Buddha Nature), in accord with the profound Mantrayana, distinguishes well what exists and what does not exist when an exceptional meditative stabilization arises.
