Centering Prayer is an approach to prayer which involves resting in God in non-conceptual contemplation, and is open to anyone seeking a deeper spirituality. This book looks in particular at how Centering Prayer can be effective at all stages of evolving consciousness. Evolving consciousness, as identified by Integral Theory, refers to different levels of human spiritual deepening. Integral Theory also proposes that when people are unaware of the stages of consciousness, they tend to believe that the perspectives of their own stage(s) are the only true or realistic views, which can lead to confusion and conflict. This book seeks to bring harmony and understanding to people at different levels and in different religious and spiritual traditions.
