I watched a woman approach Papaji a few years ago with what appeared to be a sensible, spiritual question. He exploded with anger, said that she was only interested in sex and told her to go away. We were all quite shocked because this was her first day, her first meeting. Later that day I spoke to the woman she had come with and asked her how her friend had dealt with this extreme reaction.

She laughed and said, ‘I’m so glad Papaji reacted like that. Every year she comes to India and goes to a new ashram, pretending to be interested in the teacher and the teachings, but every year she starts an affair with some devotee. That’s the real reason why she comes. After a few months she gets bored and leaves. I’m so happy that someone has finally seen through her game.’

I have witnessed countless strange reactions such as these in the teachers I have been with, all of them caused by hidden thoughts and desires that none of the rest of us could see.

There is something else that is going on when you sit in front of a true teacher. There is an effortless transmission of peace that stills the mind and brings an intense joy to the heart. None of this will be recorded in the dialogue that is going on between the two of you. It is something very private, and only the two of you are in on the secret. Words may be exchanged but the real communication is a silent one. In such cases the teacher is often reacting to the temporary absence of your mind, rather than the question you asked a few minutes before, but who else can see this?
