Zen is a communal practice; it is also a commitment. Zen, ultimately, is a path of service to all beings and to each other, this commitment or vow is expressed in the Four Bodhisattva Vows. Showing up to practice together is an expression of that commitment. In some ways, commitment in Zen is like the Metta or Loving Kindness practice. We start with making a commitment to ourselves then extend that to loved ones and friends and continue extending to community and ultimately to all beings.
