There are two types of energies of Supreme-Superior & Inferior.Let us look at both one by one.
Krishna says, “Earth,water,fire,ether,air,mind,intelligence,false ego-all together these eight constitute my separated material energies.”
We can see,the first five components,namely Earth,water,fire,ether & air not only make the entire cosmos but also the physical bodies of all living organisms including humans.The rest three components,Mind,intelligence & false ego come under the metaphysical aspect.
Krishna says, “Besides these,there is another superior energy of mine which constitute living entities who are exploiting this material,inferior nature.”
That means the Soul of living entities is the superior energy of Lord.But why is Soul considered to be much more important than mind & intelligence?
It is because the quality or the nature of a soul is similar to the supreme/Super Soul.Soul is a fragmental part & parcel of Lord.(For better understanding refer to the post ‘Soul & Super Soul’)
While exploiting the inferior energy,Superior energy forgets his real spiritual nature.This forgetfulness is due to the influence of matter upon living entity.The false ego thinks ‘I am matter, material acquisitions are mine’.But when the living entity becomes free from illusory material energy,he attains the stage of Liberation.
