This requires great sensitivity and therefore great intelligence. Not conclusions, not experience, but intelligence. To be intelligent you need tremendous sensitivity. There can be sensitivity only when the body is also sensitive –

Just listen, watch all the activities of yourself: the way you talk, the way you eat, the way you walk. Don’t correct the walk, don’t correct the way you eat, just watch it, so that by the very watching, you become astonishingly sensitive. This requires great sensitivity and therefore great intelligence. Not conclusions, not experience, but intelligence. To be intelligent you need tremendous sensitivity. There can be sensitivity only when the body is also sensitive – how you observe, see, hear. Then, out of that minute observation, without any choice, without any evaluation or judgment, condemnation or comparison, just to observe – out of that observation, you will see that your body becomes extraordinarily alert, sensitive, and therefore the whole of your brain, the mind, the whole of your entity becomes sensitive.
