The sky is blue. The grass is green. The snow is cold. The rain is wet. The sun comes up each day in our world and goes down. That is the way things are. There is nothing to think about. There is nothing to worry about. That is the way. When you are in touch with the way, you have peace.
Is there a self? Is there not a self? Who is thinking these thoughts? Where did I come from? Why am I here? Where am I going? Really? Live in the moment. Be present at all times. Questions with no answers are not worth pursuing. Trying to sound wise on metaphysical meanderings is of no use.
We are born, we age, we die. Why all the angst? That is the way. Did you think it would not happen to you? A person of 18 years will not look the same as that same person at 50 or 75 years. Only the foolish try to hang on to the past. The wise embrace today. The sage does not worry about death. He makes peace with death before it is imminent. When he takes tea, he takes tea. When he sleeps, he sleeps.
