Bhagavad Gita (Chapter – 4, Verse – 7)

Whenever there is rise in evil, whenever ignorance and arrogance rise, obviously the result is suffering. The Lord does not drop physically somewhere from the heavens. The metaphor must be understood. It does not mean when there will be people of certain kinds who would be behaving in evil ways then some avatar will descend from the skies. What it simply means is that whenever the ego inflates, the consequence is suffering and suffering itself calls for its cessation. You do not like to suffer. This call of cessation of suffering itself is the coming of the Lord.

The ego is caught in a quandary. It likes to be inflated but it does not like to suffer. But the natural consequence of its own inflation is suffering. It likes to be big, it likes to act powerful, but the more powerful it acts, the more it suffers and suffering is something it does not like. So the very inflation of the ego, the very rise of ego, the very increase of evil, is also a parallel increase in the urge to dissolve the evil, the suffering, the ego. The Lord doesn’t come from anywhere; the ego sees its own futility, its vanity and surrenders.
