Similarly with Agnihotra (a ritual performed to purify the atmosphere using fire), they have found how the virus that catches on to trees can be eliminated. Now trees can become healthy, just with Agnihotra, where they put certain herbs in the fire.
So, yagnas are ancient techniques where you use different herbs and create that atmosphere using the five elements, i.e., Water, Earth, Fire, Air and Ether. The thing is, you need to have people who know how to do this correctly.
Do you know, this science was almost dying, that is why we started a school here.
In 1980, when I was touring Germany, and giving lectures in different universities; at the University of Tubingen, some people took me to their manuscript library. They said, ‘Sri Sri, see, there are so many Sanskrit manuscripts here, thousands of them. Do you have some scholars who can decode these things? We are unable to get scholars to decode; we are preserving the manuscripts.’
They have maintained the manuscripts so well in Hamburg University, and in Tubingen they have filmed them.
Then I came to India and held several conferences. The scholars who knew how to read these ancient scriptures, were old, and did not want to travel. They were already in their sixties and seventies, and the youngsters had no idea about the scriptures.
