How to change someone’s nature

Sri Sri Ravi Shankar: 

Why do you want to change someone else’s nature? If you want to change someone’s nature because what they are doing is troubling you, then it is never going to change! However, if we wish that they change their nature because it will harm them, if this is our perspective, then there definitely is a possibility of change.

Why is it that people are unable to bring about a change in another person's behavior? This is because they are caught up with themselves. If you say, ‘Change for me’ then nobody is going to change.

Why or how is it that only a Guru can bring about a change in a person? It is because a Guru never wants anything for himself. A Guru wants transformation in someone only because what the person is doing is harming himself or herself. A Guru looks at people with this compassionate perspective which is why people transform when they come to Him.
