We need to be continually vigilant about our own mind. The slightest unmindfulness can invite negative visitors into our mind and pull us away from our innate Divine Self. How do you know you have moved away from your Soul? You will feel a sense of loss of peace of mind and focus on the task at hand. Lift your mind and yoke it with your Higher Self; that is yoga. Yoga is being in union with your own Divine Self! That is where all happiness is waiting for you!
