Reidan Jichi (冷暖自知) Meaning
Meaning
Whether water is cold or warm, you only truly know by drinking it yourself. The phrase points to the kind of understanding that cannot be handed over through explanation, only discovered through your own direct experience.
Origin
It comes from the longer saying "Like a person drinking water, one knows for oneself whether it is cold or warm." In the Platform Sutra of the Sixth Patriarch and in Case 23 of the Gateless Gate (Mumonkan), a classic Zen collection of teaching stories, a monk named Huiming uses these words to describe the moment he grasped the teaching of Huineng, the Sixth Patriarch of Chinese Zen. Since then, Zen teachers have used it to stress that insight must be lived, not just learned.
How it helps with everyday worries
When you are wondering whether to change jobs or whether a path really suits you, it is natural to read reviews, ask friends, and gather opinions. Yet the more you collect, the foggier things can get. Someone else's "it was cold" or "it was warm" describes their glass of water, not yours. Their stories can inform you, but they cannot taste for you. Sometimes a small, real step, such as a conversation, a short trial, or a visit, tells you more than weeks of thinking. The same is true with people. You may hear that someone is difficult, then find them quite different when you actually meet. And when you feel that no one understands what you are going through, this phrase offers quiet reassurance. What you feel is real to you, even if you cannot explain it well. Being hard to put into words does not make it any less true.
A small practice for today
Today, slowly drink a glass of water or a cup of tea and simply notice its temperature and taste without describing it. Let it be a minute of trusting your own senses rather than anyone's opinion.
