He also explains the vast recurring cycles of civilization (yugas), affording a profound understanding of history and the ever-changing panorama of turbulent world events.The Holy Science demonstrates, by explanation of parallel passages from the Hindu and Christian scriptures, the essen­tial unity of the great religious teachings of East and West. With incomparable wisdom and discernment, Sri Yukteswar explains the universal evolution of consciousness, energy, and matter — the entire spectrum of experience that we call “life.”The author provides an authoritative foundation for a purely holistic view of man and the universe — and shows how that view supports the principles of natural living in body, mind, and soul. Rooted in the deepest truths of religion, it yet offers practical advice for fulfillment in everyday living, by delineating the physical, mental, moral, and spiritual principles that govern the expansion of human consciousness.
