Right or Wrong

A thief went to one sage and asked the sage to take him at his disciple, with one condition: to not ask him to leave his stealing habit.
The sage agreed and said OK, I will not ask you to leave your habit, but you promise me that whenever you go for stealing, just think first is that right or wrong. The thief agreed and became disciple.

That time onward the thief whenever will go for stealing, he will always think that he is doing right thing.......this went on for some time and one day finally his mind said stealing is bad..........and ultimately he left stealing...........

Moral of the story: We are what we think.
