Avatamsaka Sutra or Garland Sutra states:
‘All things are but created in mind.’
There in all living beings are three karmic functions: first, karma
operating in the body, physical behavior; second, karma operating
in speech, verbal behavior; and third, karma operating in thought,
pondering and considering—mental behavior that exerts control over
thought, action, and speech.
Put another way, physical and verbal behaviors are both subject to
the manipulation and influence of the faculty of mind. Virtuous mind
arising and thought astir lead to positive behavior in the body and
speech; evil mind arising and thought astir result in negativity, missteps
and vileness. Hence the Buddha‘s teaching on how the faculty of mind
and behavior interact.
