Q: Gurudev, after doing the Kriya, many times I find myself smiling unconsciously. When I am alone also I keep smiling. I myself don’t know that I am smiling. Everybody thinks that there is something wrong with me. What do I tell them?

Sri Sri Ravi Shankar: You should take a serious look at yourself if everybody thinks that there is something wrong with you. You must take a serious look.
If everybody is saying that then it is not okay. You must consider their opinions.
Here, I won’t say, don’t be a football of other’s opinion.
What you feel is one thing, and how you express yourself is another thing. You may be feeling very calm, very happy, but when you express that, you should see, how you can express it and where you should express it.
