Integrity is what you do behind closed doors or when you think nobody is watching. Integrity is the true essence of who you are, your beliefs and your values. Reputation is the public perception of who you are. It is how others view your integrity or strong moral principles.
Metta sees truly that our integrity is inviolate, no matter what our life situation may be. We do not need to fear anything. We are whole: our deepest happiness is intrinsic to the nature of our minds, and it is not damaged through uncertainty and change.
In business, integrity is just as important as in any of the great public offices... but I believe one of the first and fundamental obligations of competent business leadership is above all to protect the reputation and integrity of the business - to that degree the integrity of the business is the integrity of the leader.
