The reply was beautifully explained by an American, F. Shant, PhD from St. Louis Uni., 30+ years Practicing Practical Hindu Spirituality. Do read and keep forwarding
Human eyes and recording equipment can’t record what dogs and cats see at night. Then came infrared cameras. We realized shortcomings of our eyes. Microscope started seeing cells. Scientists went on to build bigger and bigger microscopes, electron microscopes, just realized that smallest part of independent existence, has many parts. Then came CAT scans, PET scans, MRIs, we started seeing what nobody knew existed.
When scientists thought we knew everything, came dark matter. Never seen or heard of earlier, but now believed to occupy about 75% of space. Again we knew we don’t know anything.
AS A TRAINED SCIENTIST I CAN SHARE THE REAL SECRET OF WHY…..
For seeing Shiva on that mountain, we need different eyes. Once we have those, He can be seen not just on Kailash by scientists, but everywhere and anywhere, because that mountain is not the only place He is, He is everywhere.
This separate set of eyes required are those of mind, those of heart, those of dedication, those of surrender.
Once that comes, rest all falls into place.
