Tell me how you understand Rabindranath Tagore's "Sit quietly, my heart! Let the world find its own way to you."

I don’t know where to start when I am happy, but sadness comes from my heart. Life is constantly giving new hope, but it also brings too much confusion. The face that smiles silently when in a daze is so happy and peaceful, as if life is always full of sunshine and beautiful scenery, but when you raise your head and close your eyes, you feel that silent sigh, and only you understand everything. Those tears flowing in my heart are filled with melancholy. Why is life always so bad, the future is unpredictable and everything is uncertain.

From the time I started talking about life with others, I knew all the truths about survival. I have spoken words of wisdom and clarity that changed the lives of others, and I have spoken out the true meaning of life so thoroughly, but why can’t I say anything that can convince me? It's all lies, lies that can only work on other people. Be quiet! My heart, I have been praying for myself, and I have been searching for myself in my heart, but I find that I have become farther and farther away from my heart, and I have gone too far. Maybe life should be more grateful. I am grateful for the first light of the morning, and grateful to God for allowing me to return to the place where I started. Sit still! My heart, don't raise your dust. Let the world find its way to you.
