According to Osho, Indians hang around in threes as a sly joke: one can read, one can write, and the third just enjoys basking in the aura of intellect. He uses the gag to expose second-hand knowledge and social posing - real intelligence is not borrowed from company; it arises from direct understanding, awareness, and lived experience.
It’s a joke that says two know a little and the third tags along to feel smart, reminding us not to pretend but to understand for ourselves.
