The fifth Field of Zen Practice is living according to moral Precepts. The Buddhist precepts guide our ethical conduct, ensuring we minimize the harm we do to self and others. Such conduct is a prerequisite for the peace of mind we need for spiritual practice. The precepts also serve as valuable tools for studying the self; when we are tempted to break them, it alerts us to our self-attachment and reveals our persistent delusion of self as a separate and inherently-existing entity. Keeping the precepts familiarizes us with acting as if the self is empty of inherent existence. This episode is the first part of chapter five of my book-in-process, The Ten Fields of Zen: A Primer for Practitioners.
