One day, a certain scientist came to visit Luang Por [Chah]. Speaking as someone who had practised meditation and felt qualified to make a comparison, he was of the opinion that as a means of realizing the truth of things, science offered a path that was more effective and more verifiable than Buddhist training.
Luang Por was unimpressed. ‘Don’t you think it’s possible,’ he asked, ‘that you’re putting forth this claim without a full knowledge of the results of Buddhist training?’
He gave two similes: it was like a man putting one short arm down a hole who concludes that the hole only goes as far as his arm; it was like a short-sighted man who concludes that there are no such things as airplanes in the sky because he’s never seen one.
