I am sorry that your friend died, and that you feel the loss so profoundly.
And yet ... we can experience that there is no birth and death, nothing coming or going ... like waves that are just the sea, that rise and fall on the sea, yet the sea remains all along. So, there is no coming and going, not a drop lost from the sea.
And yet, and yet ... your friend has died, and your heart was broken.
If I may, I will dedicate today's Zazen to your friend.
Gassho, Jundo
