When you go, go.
When you eat, eat.
When you sit, just sit.
This is a famous Zen canon that reminds us of a simple but forgotten truth: most of our suffering comes not from what is happening now, but from what is happening in our minds.
We eat breakfast, but mentally we are already at work. We are resting, but thinking about unfinished business. We talk to loved ones, but worry about the future or go back to the past.
Our body is in one place, and our mind is somewhere far away.
Zen teaches you to return to what is happening in the moment. Don't try to live yesterday, today and tomorrow at the same time. Don't look for ideal circumstances to feel a happy ending.
When you walk, feel the ground beneath your feet. When you drink tea, feel its taste. When you look at the trees, just look, without turning every moment into another thought. This does not mean to give up plans or stop thinking about the future. It means learning to live while life actually happens.
Maybe peace begins not when all problems disappear, but when you mentally stop creating new ones.
