The primordial Buddhas are saying,
  "Not doing wrong action,
Sincerely doing every kind of good,
naturally clarifies this mind.
This is the Teaching of all the Buddhas."
This is the universal precept of the Seven Buddhas, our Founding Ancestors, and is truly transmitted by earlier Buddhas to later Buddhas and is received by later Buddhas from earlier Buddhas. It is not only the Teaching of the Seven Buddhas but of all the Buddhas. This principle must be investigated and mastered through practice.
