Actually leader is Kṛṣṇa. Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66). He is actual leader. So don't follow all these nonsense things. Don't follow all these "isms", you'll spoil your life, because you are not this body, that is the first . . . tathā dehāntaraṁ prāpti, dehino 'smin yathā dehe (BG 2.13). So everything clearly explained in the Bhagavad-gītā. So instead of accepting these blind leaders, we should know who is actual leader. Kṛṣṇa is the leader. We'll, if we take leadership of Kṛṣṇa, then our life is perfect; we could properly utilize the utility of human life. Otherwise we have been mislead.
Now Kṛṣṇa is therefore explaining that the, whatever you are seeing in this material world . . . what is this material world? This material world is combination of the spiritual and material energy of Kṛṣṇa. Parasya brahmaṇaḥ śaktiḥ. There are two different energies of Brahman. Sarvedam akhilaṁ jagat. What is this Calcutta city? Calcutta city means the earth, water, air, fire, sky. These are material elements, gross elements. Mind, intelligence and ego, these are the subtle elements. These eight elements, Kṛṣṇa's energy, and beyond this energy, aparayam, these are inferior energy. Beyond this inferior, super . . . inferior energy there is a superior energy. Apareyam itas tu viddhi me prakṛtiṁ parā (BG 7.5). Another superior. What is that superior energy? Jīva-bhūta, the living force, the living entity.
