The Wizards' Oath
Taken from Diane Duane's 'Wizards' series.
In Life's name, and for Life's sake, I assert that I will employ the Art which is It's gift in Life's service alone. I will guard growth and ease pain. I will fight to preserve what grows and lives well in its own way: nor will I change any creature unless its growth and life, or that of the system of which it is part, are threatened. To these ends, in the practice of my Art, I will ever put aside fear for courage, and death for life, when it is fitting to do so - looking always toward the Heart of Time, where all our sundered times are one, and all our myriad worlds lie whole, in That from Which they proceded.
