For nearly four decades Mark Spencer has balanced his career as a dental surgeon with his passions for ocean exploration and underwater photography. His photographs - sometimes of rarely seen shipwrecks hidden in the deep - have been featured in publications such as National Geographic and Australian Geographic.
A scientist at heart, Mark has long held a curiosity about the deeper levels of conscious awareness he experiences in meditation and how these experiences appeared to correlate with his ocean diving.
Part autobiography, part science and part philosophy, this book is the culmination of Mark's decades-long research into these correlations. He explains why we all need to become deep-sea 'divers' in the one ocean of consciousness which he argues is the unified field currently being explored by modern physics. The implications are profound for our physical, mental and spiritual development and also promise surprisingly practical solutions for world peace and harmony.
