This is a beautiful piece of writing. I had not heard the term "ichigo ichie" before and I love the idea of connecting it to grief.
I practice many forms of meditation, and I've recently been learning about tea ceremony as a way of contemplating impermanence.
I aspire one day to always view the world as ichigo ichie, and to cherish every moment of my life.
I hope I've used that term correctly. Thank you for sharing it. Thank you also for being willing to share painful parts of your life.
