In books like Embyogenesis and Embryos , Galaxies, and Sentient Beings, author Richard Grossinger brought together the subjects of biological embryology and the esoteric process of human consciousness becoming embodied ("The embryo is the universe writing itself on its own body"). In Dark Pool of Light , his latest creation, Grossinger weaves neuroscience-based behaviorism and the phenomenology of "being" and reality together with psychological and psychospiritual views of "that single thing which is most difficult to understand or vindicate: our own existence."
 
In 2008 Grossinger began studying with noted psychic teacher John Friedlander, who helped him refine his vision of cerebral and somatic awareness to still subtler levels. " Dark Pool of Light began unnamed in the journals of my psychic work with John Friedlander," says Grossinger, "not so much a record of actual practices as insights from them and extensions out of them." An expansive inquiry into the nature of consciousness, the series examines the tension between the scientific and philosophical, and psychic views of the same phenomena, and includes "field notes" and experiential exercises that invite the reader to make their own explorations.
 
Dark Pool of Light is divided into three volumes: in Volume 1, Grossinger begins with the scientific and philosophical, analytical views of reality, exploring the science, parascience, philosophy, and psychology of consciousness. Covering topics as diverse as current discoveries in neuroscience and the philosophy of the ancient Greeks, the book gives a broad overview of the bodies of knowledge concerning the nature of reality and consciousness. Volume Two discusses the similarities and differences between European esoteric traditions and Buddhism in their approaches to the subjects, and gives a detailed description of the psychic training Grossinger undertook that informs much of his worldview. This expansive inquiry into the nature of consciousness ends with this third volume in the series, The Crisis and Future of Consciousness. Grossinger addresses the perennial question of evil and shares the author's hopes and fears for the future of humanity. While wisdom gleaned from such seemingly disparate sources as science, philosophy, religion, and spirituality might appear "very, very different things," Grossinger nevertheless finds their meeting place in subjective, lived experience.
