What is the essence of a man?

The essence of man here on earth is to worship God.That is what the scripture says >>>>>>>>>>>>>>>>>>>>>>> Everything in the cosos / universal is basically energy. Human or man exist with a composite of energy of matter and energy of mind. The basic energies of all matter exist in the form of four abstract elements which give matter its characteristic of solidity, heat, fluidity and motion (air). The mind too exists in the form of energy but the strenght of each mind is difference; the mind strenght of a moral human is more higher than the mind strenght of a immoral man.
