As a child I would ask my father if we take all the minerals, vitamins, amino acids, hormones through injections tablets or in syrup what is the need to take food ? My father a botanist of 1940s scolded me for such funny ideas. Minerals need to be taken in the form nearest to their form in nature : from plants or animals for being absorbed and accepted in our body . What Ayurveda or science of life is all about is getting minerals, vitamins, micronutrients from plants for strengthening the human body. A healthy body is not a body free from disease but a body sound physically, emotionally and mentally and at peace with itself. Plants are capable of providing all of this and take away all the carbon di oxide from the atmosphere. Once an "angrej " (or Englishman is a common term used to describe a foreigner visiting a village ) saw lot of smoke coming in a room called kitchen with no proper outlet and women suffering inhaling the smoke. He said why don’t you use improved stove ? The person accompanying "angrej " showed him an improved stove lying in the corner of the same room filled with smoke. Rightly someone remarked what is needed is not improved stove but education about environment. Man needs to learn simple things of life from someone with whom he or she grows as a child. Parents are first teachers. If they will teach their children to love nature protect nature and live with nature in harmony world will be a better place to live. Someone was very kind to me to suggest that I should not bother much about environment but what I am trying to say is to teach the teachers: parents to save environment for their children.
