All the creation and existence is possible between both these concepts (process). We are very familiar with Yoga but not Yagya. Yagya is one of the best tool in solving any kind of problem. Same like yoga, there are so many type of Yagya. Simple type of Yagya is, we offer few herbs, Ghee, wood, sweet etc to fire. Fire is divine mouth. So in Yagya we offer divine food to God and pray for universe and individual welfare. After receiving all these divine articles and our prayer, God multiplies and return back to universe for our betterment. At a time of Yagya we feel divine fragrance around us, this smog and fragrance nourish all humans, plants, animals and birds. Sound healing is an important part of Yagya (agnihotra).
