Arjuna is convinced that Krishna is the divine being and requests Him to describe His divine glories like divine nectar further. He is asking for him to reveal his glory and explain to him what his different forms are. Posing the question of which form he should grasp or hold on to. Earlier, Krishna means that he is Prakriti, which is defined as the prime material energy of which all matter is composed. "..is made of eight elements: earth, water, air, fire, akasha (“sky” or “space”), mind, intelligence, and ego. However, beyond his prakriti is another, higher form. This other form created and supports everything that exists and destroys it when the time comes. Though he has created many mortal bodies, Vishnu’s true self was never born and will never die. He is beyond such things; his true nature is eternal and changeless. "
