I think that we all have those times, when our mind is busy with thoughts, and our mind tries to overcome and solve problems. Something that helps me is to come back to my breath - to trust the breath, and not the mind.
Recently, I was lying awake in bed, thinking of my loved ones and the challenges that they have in their lives. I felt overwhelmed thinking about it, and my thoughts were creating chaos. I remembered the words that Hang had shared with me that day, after she listened to a Dharma talk by Brother Phap Dang, that the mind will try to overcome problems, and instead to "trust the breath". I came back to my breath and found instant relief. I breathed peacefully and smiled at my thoughts, and smiled at my loved ones with love and understanding. My peace and calmness were restored.
