Thich Nhat Hanh DEP.

“Please do not build a stupa for me. Please do not put my ashes in a vase, lock me inside, and limit who I am. I know this will be difficult for some of you. If you must build a stupa though, please make sure that you put a sign on it that says, ‘I am not in here.’ In addition, you can also put another sign that says, ‘I am not out there either,’ and a third sign that says, ‘If I am anywhere, it is in your mindful breathing and in your peaceful steps.’”
