Conditions bring about causes and causes give birth to effects. There is nothing haphazard. Causes, conditions and effects bring about other or further causes and effects.

From Zen Marrow Talk One:

Guo Gu often speaks about and teaches the Four-Fold axiom of Chan:

  • Outside of Doctrine / Chan is not built on words and language
  • Chan is not based on labels
  • Chan Directly points to the Human mind
  • All beings can obtain Buddha-hood.

All beings already have Buddha Nature. One’s Buddha Nature is not recognized because of the dust of vexations. Vexations are things that cause one to be annoyed, frustrated, or peeved. One’s true nature is being free from anger, aggravation, annoyance, bother, frustration, etc.
