There are many dimensions of fire, within and without. Let us look at the three forms of fire that burn within us. One is known as jatharagni. Jathara means stomach or digestive process. Without a little bit of fire in your belly, you cannot digest the food that you eat. Food is functioning as fuel that you need to break down in order to release the energy that you need. If the digestive fire is well-nourished and well-supplied with fuel, it also becomes reproductive fire. Both digestion and reproduction depend on jatharagni.
