All the five elements have been created by the will of the Supreme. They must be used with reverential care and vigilant discrimination. Reckless use of any of them will only rebound on you with tremendous harm. Nature outside must be handled with discretion, caution and awe. It is the same with our inner ‘nature’ and internal instruments too! Of these, two are capable of vast harm – the tongue and one’s lust. Since lust is aroused and inflamed by the food consumed and the drink taken in, the tongue needs greater attention. While your eye, ear and nose have single uses, the tongue makes itself available for two purposes: to judge taste and to utter word – symbols of communication. You must control the tongue with double care, since it can harm you in two ways. Sage Patanjali, the author of Yoga Sutras has declared that when tongue is conquered, victory is yours!
