Why Does Human Grow

Why must we leave childhood's paradis ?
If you had ever asked?

For many of us,childhood was the best part of whole life,especially for many artists and writers,back to childhood feeling were their dream.
But,why in childhood everyone was innocent and pure ,but,growing up makes human-beings fallen?
Because desire kill every child !
We asked God,why do you kill children by desire?
He answered us,because it is our freewill to make decision ,
If you pursue spiritual reformation or not!

God! Don't be so mean to us!
