In this dharma talk I share my latest understanding of the Practice Principles, originally formulated by Joko Beck and as interpreted by my teacher Barry Magid. The practice principles give us a condensed way of understanding ordinary mind zen practice. However, they do miss out some important aspects of practice, such as the importance of supportive relationships and mutual recognition. This talk covers how they are a re-working of the four noble truths and the four great vows. The two couplets represent the Two Truths, the absolute or ultimate truth and the relative or conventional truth. The first two lines focus on how suffering arises in our everyday lives of problems and relationships. They also give us a clue to the ending of suffering. The final two lines emphasise the koan aspect of zen embodied in our zazen practice of just-sitting. Paradoxically, the end of suffering is the end of the resistance to suffering.
