Also enclosed is one article sent to me by Hayagriva about the new discovery which creates turmoil and confuses the physicists. The material scientists, they are discovering so many particles, but they have not yet discovered the soul. In Bhagavad-gita we learn:
apareyam itas tv anyam
prakrtim viddhi me param
jiva-bhutam maha-baho
yayedam dharyate jagat
[Bg. 7.5]
That the jiva-atma is the superior particle and these other particles are all inferior. So this is their business, to discover the inferior particles and neither have they discovered the superior particle which is one ten-thousandth the tip of a hair. Simply they are wasting their time.
