Remember, you are not so miserable as you have made yourself out to be. You are God, too, and cultivating this constant awareness within you will help keep you from false attachments, from identifying yourself with your body, mind, and senses. So you must say to yourself, “Body, mind, and senses are mine, but they are not me, for I am that eternal flame which is not subject to change, death, and decay.” This awareness should always be with you.
When the senses are well-controlled and withdrawn from contact with the objects of the world, then sense perceptions no longer create images in the mind. The mind is then trained in one-pointedness. When the mind no longer recalls thought-patterns from the unconscious, a balanced state of mind leads to a higher state of consciousness. A perfect state of serenity established in sattva is the highest state of enlightenment. The practice of meditation and non-attachment are the two keynotes. A very firm conviction is essential for establishing a definite philosophy of life.
It is impossible to understand what exists through reasoning or intellectual debates. Absolute truth cannot be scientifically proven because it cannot be observed, verified, or demonstrated through sensory perceptions. (...) This is why scientists cannot come to any objective conclusion about the immortality of the soul and the afterlife, and in any case, nothing could convince them. (...) The objective world is only half of the universe. What we perceive through our senses is not the world in its entirety. The other half, which includes the mind, thoughts, and emotions, cannot be explained by sensory perceptions of external objects. (...) The soul has not been created. It is essentially consciousness and is perfect. After the dissolution of the gross body, everything remains latent. The soul survives.
