Learn to love all the things of the world, just as means but don’t get attached to them. This is the secret—the philosophy of non-attachment.
When the senses are well-controlled and withdrawn from contact with the objects of the world, then sense perceptions no longer create images in the mind.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.
If you really want to enjoy life and be happy, learn to practice and understand the philosophy of non-attachment.
