The author approaches the study of the structure and manifestation of the human psyche from three angles: yogic sadhana, psychological experimentation and Vedic revelation. These supposedly irreconcilable sources are harmonised, "leaving thus the way to re-emergence of the human psyche in all its non-spatio-temporal immensity and purity".
The part of the book dealing with Sri Aurobindo and Jung was published in 1986. With the addition of the Vedic perspective, the study of psychology gains in depth while spirituality is "enlarged in the historical perspective".
In the process our understanding of the Veda itself is enriched as the "Jungian perspective adds to the feasibility of its psychological content" and the "Aurobindonian perspective unfolds the treasure of spiritual knowledge embodied in it."
