The Meaning of Rigpa Being Permanent
When the dzogchen texts assert that rigpa is an unaffected (' dus-ma-byed, unconditioned, uncollected) permanent (rtag-pa) phenomenon, we must understand the meaning carefully. Unaffected, here, means that it is not created anew each moment and does not organically grow from something, as a sprout does from a seed. Thus, it is uncontrived (bcos-med) – not made up or fabricated, under the influence of causes and conditions, as something temporary and new. Moreover, its having good qualities does not depend on causes and conditions. It is permanent, not in the sense of being static and not performing a function, but rather in the sense of lasting forever, as do its qualities.
In each moment, however, rigpa spontaneously gives rise to and is aware of different objects. In this sense, it is fresh and clean (so-ma). Although its nature never changes, these aspects change. Focusing on this feature, Gelug would assert that rigpa is nonstatic (mi-rtag-pa, impermanent). There is no contradiction, however, because dzogchen and Gelug are defining and using the terms permanent and impermanent differently.
