I am not a Ph.D., yet I can challenge the scientists. Why? Because I know Krsna, the Absolute Truth. Yasmin sthito na duhkhena gurunapi vicalyate: "If one is situated in Krsna consciousness, then even in the greatest calamities he will not be disturbed." (Bg. 6.22) Srimad-Bhagavatam (1.5.22) declares, avicyuto 'rthah kavibhir nirupito yad uttamasloka-gunanuvarnanam: "Great personalities have decided that Krsna consciousness is the perfection of life." This kind of knowledge is required. Not that we do some research, come up with a theory, and after fifteen years say, "No, no, it is not right - it is another thing." That is not science; that is child's play.
