This is a revised & enlarged edition of the book "God and Self-Realization" (Scientific and Spiritual View). Although God is one & Truth is one, but there are many misconceptions between the Spirituality & Sciences. None has synthesized both to remove the differences. Now the latest Cosmological researches are accepting the evidences and the hand of an infinite intelligent and powerful Almighty God in the creation of the universe. I noticed that many authors who are neither spiritual nor have enough knowledge of yoga, sciences & spirituality are creating misconceptions and confusing the readers. This book is a rare attempt to remove those misconceptions and confusions. God & Self-Realization is revised edition is a rare attempt to write a spiritual cum scientific book. It correlates our latest scientific cosmological researches and technological developments with the universal science of Yoga and Scriptures. The book deals with the most common misconceptions and confusions in the minds of educated people like the difference between: Illusions--Delusions–Maya; Guru–Teacher– Instructor, Information–Knowledge; due to increase of information our ignorance is increasing; Creation–Creator; Belief–Faith; Life Energy (prana) – Physical Energies; Avatars–Self realized saints; Scriptures–Ordinary or Holy Books, Magic–Miracle, Proof–Verification; Scientific Laws are beyond derivation and proofs; Are the Scriptures or Shastras are Myths or Reality; Who is writer of Vedas and Scriptures; Misconceptions about dreams and death etc. Due to teaching of sciences in a wrong way much confusion and misconceptions are created in our minds. It is due to the faulty system of education and faulty teaching. For example many began to think that information is knowledge; science and technology can do anything (even impossible) and there is no need of the creator for the creation of the universe. Most of the students generally lost their faith in the existence of God and began to ignore their religion. They began to doubt upon the miracles performed by the saints and apparently become atheist. The author has tried his best to remove their doubts and misconceptions. He has tried to convince that the sciences, the Scriptures, the religions and the yogic science are in perfect agreement with each other. There cannot be any contradiction between the religions, God and the scientific laws. The Scriptures are not myths but are full of truth. Science and the Scriptures are not contradictory to each other as said by some ignorant scientists. Both are supplementing their knowledge to each other and ultimately leading to the same Absolute Complete Truth. Due to rapid scientific and technological advancement, our old ideas and philosophies are changing and the new ideas and philosophies are taking births. Now the scientists have begun to realize that our basic identity in the world is neither mind, nor the physical body bounded by birth and death, nor time and space. But it is basically the infinite universal and eternal spirit with infinite cosmic consciousness. This consciousness is beyond time and space and is unaffected by death. The entire cosmos is a manifestation of universal consciousness. It is beyond limits, finite, eternal, and without boundaries. It is ultimately our real self. Why we have not realized this truth?
