Nam-Myoho-Renge-Kyo

Last night before I went to bed, I was still thinking about Lisa and what happened. Of course, she was still upset, rightfully so, so I told her to chant Nam-Myoho-Renge-Kyo whenever she feels angry, sad or anxious. I told her I do it and it makes me feel lighter. I hope she can do this, too, but in her own time. Then I thought to myself, yes we're problems right now, but deep down, we truly care about each other and hurt when the other's hurting. What do you think?
