Everyone is duratma, anisvaram: "There is no isvara. This is a false manifestation." That is not false. You study everything. You study even one plant. You can see so many arrangement, so many fibers. Fine fibers are coming out, and from one fiber to another. Even a small herb and vegetable, you will find there is craftsmanship. You cannot say it is chance. You cannot do it. So there is brain. That is right conclusion, "There is brain behind it," and that is theism.
