please remember what swami vivekananda told. every man is potentially great. sri aurobindo told thru meditation man can attain supramental consciousness, i.e. divinity. hinduism says, as sri sankaryacharya said "ekamadwitiyam", no differentiation between man and god, the almighty. till the electrons were found out, did we know that they exist. did we know radioactivity unless madam curie discovered it. did we know penicillins till sir alexander flemming isolated them and this one discovery changed man's longevity from twenty years to seventy years. it is sheer arrogance and audacity to say somthing is not possible till some one finds it out or some one gets the realization like sant kabir.
