This instructive book carries in itself a life-transforming value. None who reads it, with the needed interest and attention, will ever feel inclined to remain unchanged in personal nature and untransformed in conduct and character. A good deal of careful judgment and confidence would assist us in asserting that no one who reads this work, will fail to resist the readiness to make of his own will a Power that alters and exalts his own life and destiny. The work is fraught with implicit guidance for turning our personalities into forces of compelling influence and charm, and for rendering our lives into so many grand stories of the epic unfoldment of the Divine Truth we enshrine, the Divine Light we bear, and the Divine perfection we hold in our inner being.
This, then, is a simple, straightforward, inspiring book that holds out many methods for the culture and nurture of thought power. It is also a work that presents us with many useful suggestions which enable us to reach a region beyond the terrain of thought and its power, a realm of transcendental Experience and God-consciousness.
Sivananda has attempted implicitly to present in this work, a dynamic knowledge of thought power at these three distinct fields:
1. The field of higher applied psychology: Here Sivananda speaks of thoughts as forces that chisel countenance, fashion character, change destiny, and make of life an all-round success.
2. The field of a full-fledged parapsychology: This field is covered by those widely scattered passages and chapters in this work, which throw illumination on the fact that human Mind is the seat and centre of a number of supernormal powers and factors. Sivananda urges the readers to tap these powers, and to make operative in their own outer life, the various higher faculties they command.
3. The field of transcendental realization: Wherever Sivananda prescribes a method for, or speaks of thought-transcendence, he is attempting to lead us into the domains of Divine Realization in which thought ceases to be thought, and blazes into infinite Consciousness.
This work, then, represents Sivananda to the readers, in a way, as a practical psychologist, a physicist and chemist in the world of the phenomena of thought, a parapsychologist, a Yogi, and thus helps them build their future, gain their success in life, and acquire the power to manipulate thought and wrest from it the extraordinary powers it holds. The book will also help them to attain refinement and culture by thought-discipline, use their capacity for releasing wholesome, constructive and inspiring thought-vibrations, obtain by accomplishing something great and grand, peace, happiness, and gain God-realization which is the meaning, aim, and ultimate destiny of all human life on earth.
