An ecological spirituality needs to be built on three premises: the transience of selves, the living interdependency of all things, and the value of the personal in communion. Many spiritual traditions have emphasized the need to "let go of ego" but in ways that diminished the value of the person, undercutting particularly those, like women, who scarcely have been allowed individuated personhood at all. We need to "let go of the ego" in a different sense. We are called to affirm the integrity of our personal center of being, in mutuality with the personal centers of all other beings across species and, at the same time, accept the transience of these personal selves.
Once God has become a living reality for us, we simply have to love others. We cannot do otherwise. And once we live in love, we are moved quite naturally and joyfully to serve others. God is love and if we live in union with God, we have the strength and longing to love others. Service is a spiritual activity, the natural fruit of love.
