Every thought produces a strong vibration in every cell of our body, and leaves a deep impression on our sub-conscious mind. Impressions from the depth of the subconscious mind come up in the form of thought-vibrations or mental images, and direct our actions accordingly. Therefore, we are the makers of our own habits, circumstances, character and fate. These thought-vibrations are transmuted to every fibre and nerve of our physical body, and cause electrical, chemical and biological changes, affecting our physical and mental condition. Every good and sublime thought conjures a noble spirit and initiates good action, contributing to our health and happiness. This also has an invigorating effect in improving our physical and mental condition, even during moments of depression and exhaustion.
