The Field and the Dictionary

Rahul had a problem.

He had a problem and he knew the solution for it.

But the solution wasn't working.

He talked to his father about it.
He replied, "All problems we have known and will face can be formed from the dictionary.
All solutions we will ever need can be framed from the dictionary.
But reading a dictionary doesn't work. The solution you know is a sentence you have read somewhere.
It is work in the field which yields crop and not sitting in the farmhouse."
