Shambhala: Ken Wilber – Integral Spirituality
Applying his highly acclaimed integral approach, Wilber formulates a theory of spirituality that honors the truths of modernity and postmodernity—including the revolutions in science and culture—while incorporating the legacy of the great religions. He shows why full enlightenment is not possible without combining the enlightenment of the East, which excels at cultivating higher states of consciousness, with the enlightenment of the West, which offers developmental and psychodynamic psychology. Each contributes key components to a more integral spirituality.

Shambhala offers pre-order at $18 and change, but I ordered from amazon, which pre-sells the hardcover of Integral Spirituality for $15.61.
