Busy means you lost the heart and mind
It's too late to say someting to the loving person. Our loving person passed away, then we think and reflect, "I wanted to talk more with him/her." "I wanted to stay with him/her." "I wanted to do this and that." It's too late. Life is short. We all are missing the most important thing in our lives. We are not alone. We are all together interconneceted in the dharma with love.
