Joanna Macy and Molly Brown in Coming Back to Life describe processes for a Council of All Beings (pp. 149-165). Many of these also appear in the earlier book for which Macy is a co-author with John Seed: Thinking Like a Mountain: Towards a Council of All Beings.
In Coming Back to Life, these activities include Reporting to Chief Seattle (pp. 151-152). The Eco-Milling / The Evolutionary Gifts of the Animals (pp. 152-154) and The Remembering (pp. 154-158) hav similarities with The Universe Story Ritual appearing in the Deep Time portion of this Earth Empathy Website. The Bestiary is a litany of lost species (pp. 158-159). The Cairn of Mourning is similar in that it offers a ritual for people to express their grief for what is happening in the natural world. Macy points out that knowing the depth of this sorrow helps people know the depth of their belonging, "from which comes the power to endure hardship and to act for the well-being of all" (p. 160).
Finally, The Council of All Beings itself (pp. 161-165) is a longer ritual that "allows us to step aside from our human identity and speak on behalf of other life-forms. It is excellent for growing the ecological self, for it brings a sense of our solidarity with all life, and fresh appreciation for the damage wrought by one upstart species" (p. 161). The Council involves an invocation and blessing, then a process of being chosen by a life-form, a process of creating a mask and practicing moving and speaking as the life-form (with some optional small group work), then a structured formal Council of All these Beings, in three rounds. First the beings express their particular concerns that they are bringing to the Council. After each concern shared, the Council responds, e.g. "We hear you, Wild Goose." One by one they speak and are heard. Secondly, some humans are asked to step into the center and sit and listen to hear the concerns, silently listening. Third, "when all the beings have had a chance to address the humans and call them to account, a major shift occurs....Now each being has the chance to offer to the humans, and receive as a human when they come to the center, the powers that are needed to stop the destruction of the world, the strengths and gifts inherent in each life-form. Sometimes the humans break their silent listening to say simply "Thank you." Then the Council is formally ended and the energy grounded.
