All of our teachers adhere to the: Diamond Sangha Teachers Circle Ethics Agreement

As students of the Way and teachers of the Diamond Sangha, we aspire to right conduct in every aspect of our lives. In this aspiration, we have committed ourselves to maintain the Ten Grave Precepts, and we cannot improve upon them as guides and standards for our thoughts, words, and deeds. The Precepts are open to interpretation, however, so with this Ethics Agreement, we establish a clear and specific set of minimum expectations to which we should hold ourselves accountable now and in the future. We hope that publicly specifying these standards of behaviour will sharpen our awareness of ethical issues, ensure the trustworthiness of the Diamond Sangha, and serve to protect and perpetuate the Buddha-dharma.

We recognize that our work is founded on trust-the trust placed in us, each by our own teacher, to transmit the Dharma faithfully and the trust placed in us by our students to provide them respectful and appropriate instruction. In this document, we concern ourselves explicitly with the latter trust, but we know full well that the two are inseparable; that is, we cannot hope to fulfil our responsibility to transmit the Dharma if we do not endeavour to live up to the Dharma’s ethical implications.

We understand that, in our capacity as Zen teachers, we may fail our students in many ways and to vastly differing degrees. At one end of the range of severity are isolated errors and instances of neglect; it is quite possible, for example, to disappoint a student keenly by forgetting to return a telephone call. While we consider even the slightest failure unfortunate, as fallible beings we will all inevitably suffer lapses of this sort and simply have to be forgiven. The failures that concern us more, and that this Agreement is intended to address, are of greater severity-those that are demonstrably harmful to our students, either to their practice or to their general well-being, either to one individual or to a group. We commit ourselves to refrain altogether from such injurious conduct but especially from any that is intentional, repeated or protracted in duration, deceitfully concealed, exploitative of a student’s trust, or any combination of the foregoing.

To be specific, we commit ourselves:

We ask our fellow Diamond Sangha teachers and the sanghas that we serve to help us maintain these standards.
