Plotinus (204/5 -270 CE), born in Lycopolis, Egypt, when it was part of the Roman Empire, was a major figure in the philosophical school later called Neoplatonism. Neoplatonists viewed reality as deriving from a single force or figure expressed as 'the One'. Two further concepts from Plotinus, 'the Intellect' and 'the Soul', are also principal features of his philosophy. These proposals led to the work of Plotinus forming a bridge between Plato and the monotheistic religions of Christianity, Judaism, and Islam as well as Gnosticism.

Proclus - or Proclus of Athens, as he is sometimes known - is widely and rightly considered to be one of the most significant later Neoplatonist philosophers. At age 40 (c.437 CE) or so, Proclus became head of the revived Plato’s Academy in Athens. In his role for the next 50 years, the unmarried Proclus worked hard, combining effectively the roles of administrator, teacher and writer. Astronomy, ethics, mathematics, physics, theology - Proclus tackled all of those topics that together fell under the umbrella of philosophy in his time.

At the beginning of his career, Joseph Campbell developed a lasting fascination with the cultures of the Far East, and explorations of Buddhist and Hindu philosophy later became recurring motifs in his vast body of work. However, Campbell had to wait until middle age to visit the lands that inspired him so deeply. In 1954, he took a sabbatical from his teaching position and embarked on a year-long voyage through India, Thailand, Cambodia, Burma, Hong Kong, Taiwan, and finally Japan.

Jung's discovery of the 'collective unconscious', a psychic inheritance common to all humankind, transformed the understanding of the self and the way we interpret the world. In On the Nature of the Psyche Jung describes this remarkable theory in his own words, and presents a masterly overview of his theories of the unconscious, and its relation to the conscious mind. Also contained in this collection is On Psychic Energy, where Jung defends his interpretation of the libido, a key factor in the breakdown of his relations with Freud.

The basic principles that Bergson articulates, especially his way of thinking about reality as a dynamic process and his view of human beings as creative and evolving, should be helpful to anyone who seeks to go beyond simply dealing with the practical demands of daily life and consider the nature of things. Of special importance is Bergson’s claim that it is both possible and necessary to know from the inside rather than confining our attention to external perspectives and points of view. Intuition is able to get beyond what is relative and place us inside reality.

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

Originally published in 1922, The Initiates of the Flame is Hall's first exploration-and still one of his most powerful - of myth and symbol. Its chapters shine a light on the inner meaning of symbols, including the pyramid, holy grail, flame of wisdom, ark of the covenant, all-seeing eye, sword and stone, the elements of alchemy, and other gateways to the unseen world.

Published first in 1912, Psychology of the Unconscious was one of the most important stepping stones in the development of Jung’s thought and practice. It has a long subtitle: A Study of the Transformations and Symbolisms of the Libido. A Contribution to the History of the Evolution of Thought. This expressed the underlying impetus - a break from the view of the libido and its functions as taught by Sigmund Freud, which Jung had earlier adopted. It was from this point that the two approaches, which came to be known as the Swiss and Viennese schools, emerged.

The practice of what is commonly known as hatha yoga is but one of eight branches of the body of knowledge that is yoga. Yoga is a sophisticated system of self-empowerment that is capable of harnessing and activating inner energies in such a way that your body and mind function at their optimal capacity. It is a means to create inner situations exactly the way you want them, turning you into the architect of your own joy. A yogi lives life in this expansive state, and in this transformative book Sadhguru tells the story of his own awakening.
