Currently there are two CD collections by Rev. Marvin Anderson available.

The 12 Soul Powers
These timeless lectures, recorded live at Unity of Vancouver in 1996, five years before the Rev. Anderson’s transition, demonstrate the clarity, accessibility and transformative power of his work. In them, he focuses on the idea of each soul power, because, as he often reminded us, from a metaphysical perspective, everything in creation begins as an idea. The power, in fact, is in the idea itself. Our work, then, is not about exerting these powers in a direct way to produce positive changes in our lives. Rather, it is about creating an orderly, balanced consciousness through which divine ideas can express. This produces authentic spiritual growth, a new level of self-awareness and a new level of creative expression.

The Creative Process provides a spiritual framework for discovering our inner resources and authentic life purpose. We are led, stage by stage, to new levels of self-knowledge and creativity and are given a systematic way to clarify our values, goals and vision - and practical suggestions about how to live in ways that support our dreams.

In this course, as in the 12 Soul Powers (Metaphysical Lessons, Vol. 1), Rev. Anderson reminds us that everything in creation begins as an idea and that the resources required to bring the idea to fruition are inherent in the idea itself. And we, as co-creators, are the means through which God's divine idea become manifest in the material world.
