on this occasion I will try to answer about your picture @xpilar
the light within the circle is at the surface of the sun that shines on the earth with its warmth but I see there are some circles it seems that the eight circles can represent the eight planets in this universe. all of these planets get their light and energy from a single point of the sun.
If in the case of religion we can conclude also that every human being get the power of life or his living with the blessing of their efforts but we know that the result is not purely the result of us but God who gave all that because we try, others also try but God also gives the living. then whatever it is anyone just hopes to his God by way of prayer and oldest struggle.
