Each man is a microcosm of the universe. Your body is made of all the elements of the world. Nature supplied all the ingredients that make your body, which means that the universe made you by donating itself. You could accurately say that you are a small walking universe that can move, whereas the cosmic universe is stationary.
There are ways from light into darkness and from darkness into light. There are ways, also, from the gloom into deeper darkness, and from the dawn into brighter light. The wise man will use the light he has to receive more light. He will constantly advance in the knowledge of truth.
Hanuman, the devotee of Rama, said: When I identify myself with the body, O Lord, I am Thy creature, eternally separate from Thee. When I identify myself with the soul, I am a spark of that Divine Fire which Thou art. But when I identify myself with the Atman, I and Thou art one.
