Osho:
Love.
A small boy
with a penny clutched tightly in his hot little hand
entered the toyshop
and drove the proprietor to distraction
asking him to show this and that
and everything
without ever making up his mind.
Look here, my boy, said the storekeeper finally.
What do you want to buy for a penny —
the whole world with a fence around it?
The boy thought for a moment
and then replied: Let us see it.
And I say to you that ordinarily
no one is different from that small boy in this world.
But unless one is different, one is not mature.
And maturity does not come with age alone,
maturity comes through understanding the distinction
between that which is possible
and that which is not possible.
