We explore the nature of doing and not-doing, first in dharma practice generally. The Buddha’s teachings seem full of exhortations to diligence, mindfulness, and skillful effort and doing. Yet there also is a clear place for not-doing—for example, in letting go and in cultivating mindful receptivity to experience. We can also see how being a “doer” is so central to many of our identities, whether in our roles or work or even our meditation. Given these dimensions of doing and not-doing, we suggest a number of ways to inquire into and respond to our patterns and habits related to doing and not-doing, both in meditation and daily life.
