Robert Beer - The Cosmology of the Outer and Inner Universe 

Robert Beer explores the Buddhist 'Wheel of Life' painting with its six realms of cyclic existence, and the outer cosmology of our physical universe according to the Kalachakra Tantra.
The 'inner cosmology' focuses on human embryology, how dreams occur, and how the chakra systems of the subtle body are utilized in various highest Yoga-tantra practices to mimic the death experience.
