Why, then, is the mind unchanging and of infinite life? Because all notions characterized by form are subject to decline, whereas the mind, being without notions, is not subject to decline.
In Chan practice, the mind must strive to remain free of attachment and entanglement. Should these arise, we should contemplate emptiness: all things arise when causes and conditions converge, and cease in the same manner.
Every one of us possesses an innate ability for learning, referred to as “awareness.” It is through this awareness that acquiring knowledge or even wisdom becomes possible. This awareness is inherently present in both sentient beings and Buddhas alike.
Padmasambhava taught extensively about the nature of the mind. One teaching points out that failing to realize this nature is a grave fault and great shame. It has always been present, yet we perceive it only as phenomena.
Without contemplation, Dharma practice becomes impossible, leaving merely intellectual knowledge. However, knowledge itself is a conceptual mind that discriminates and attaches.
To further explain this third level, it is the "original face" that has always been unchanging, even before our parents brought us into this world. This original state is what we must uncover.
