How the jurisdiction of material science is limited
In the material energy, the principal manifestations are eight, as above mentioned. Out of these, the first five manifestations, namely earth, water, fire, air and sky, are called the five gigantic creations or the gross creations, within which the five sense objects are included. They are the manifestations of physical sound, touch, form, taste and smell. Material science comprises these ten items and nothing more. But the other three items, namely mind, intelligence and false ego, are neglected by the materialists. Philosophers who deal with mental activities are also not perfect in knowledge because they do not know the ultimate source, Krishna.
