It is necessary to have a great deal of scepticism. It is necessary to never say, ‘Yes,’ but to say, ‘No,’ and inquire. Most of us are yes-sayers because we have been trained from childhood: the father, the mother, the priest, the government, everything around us is so conditioned and influences us so that we just accept. And therefore we don’t question. When we do question, we ask silly questions. To ask a very serious question, the right question is very important, because when you ask the right question, you will get the right answer.
