I have recently discovered that I made a mistake in the commentary on how to practice the details of the Medicine Buddha sadhana. In particular, at stanza 11, and at the very end of the sadhana, there is mention of the expanse of Primordial Purity. When I had prepared the commentary, I had understood that this lies within our heart. But I have since discovered that the expanse of Primordial Purity may be referring to a way of appreciating experience as much as a location. Thus, when we recognize the purity within our own mind, Primordial Purity is everywhere, and beyond concept and limit.
I am very sorry for any misunderstanding my error may have caused. Thank you.
