Necessity is the mother of invention.

Man alone can change the shape of his world, because man masters the nature not by force but by understanding.

The civilization walked on the basis of requirement for which we have mastered the art to convert the nature to

make us comfortable.

We have invented what we need and invented everything to keep it under control by our own way.

Advancement &

Development

Conventions like lamp lighting, camp fire, fire works and dowry

killing still with us.
