The Kagyu system refers to those who manifest clear light mind by relying on the methods for penetrating vital points of the external and internal body as those who progress through graded stages of methods. Such practitioners manifest clear light mind by progressing through stages. Those with sharp faculties, however, may be practitioners for whom everything happens at once. The Nyingma tradition of dzogchen also distinguishes between these two types of practitioners. Those who manifest rigpa, pure awareness, by training through stages involving various practices with the energy-winds, tummo, and so forth are those who progress through graded stages, while those for whom everything happens at once achieve the same by relying solely on meditation on a nonconceptual state of mental consciousness without the practices of the energy channels and energy-winds.
