How do I become a God? I am fed up of ill this humanity
You need to leave humanity behind. Become an avatar in the himalayan mountains.
How do you define godhood?
Your body is a collaboration of trillions of individual living cells, individual organism. Every decision you consciously make affects them. At whims you decimate millions, with mercy to yourself you allow millions to grow. How wide must one' domain be for power to matter? If you held domination or abandonment of all life on Earth there would yet be life elsewhere out of your reach, that you would also tire of. Even if you had complete omniscience and control over all the observable universe, over all time and all possibilities of every outcome from every spatial coordinate in creation, there would still always be more that you could never hold control of.
Such is the tragic comedy of life. We are the creators, cursed in our craftsmanship with experience. You are both the fingertip and nerve impulse of God. You are the cell deep inside your own body. Your suffering comes not from the inability to be a god, but from the realization that you already are one, and you have done far less than you could have.
