He is the sun who provides warmth and light to all; who pulls the water from the water bodies and holds them in the clouds; who then bursts these clouds in the form of rain for the benefit and prosperity of the world.
He is the heavenly nectar, amrita. Just like by consuming amrita, man escapes death and becomes immortal; one who gets God, in other words attains moksha, escapes from the cycle of life and death. Hence forever elluding death.
For the smooth functioning of the nature, creation and destruction are two important tasks and both of these are performed by God. He is the one who timely annihilates different worlds. This also proves that one should consider death as destined by God; it happens only when he thinks it's time for somebody to leave this earth and he knows best.
