What is light?


Is the following paragraph correct?

“What is light? Sometimes it is on and sometimes it is off. Light is a part of fire. Man has always craved for light and has travelled long in search of it. There is light everywhere in this age. Roads, houses and bazaars are well-lit. But some people think that the inward light in the heart cannot be extinguished. Often, bazaars are illuminated but the hearts are darkened.”

Acceptable as it is grammatically correct but ‘Light is a feature of fire’ seems better to me.
