I can’t lay claim to understanding all the implications of this verse, but it certainly sounds logical: When the conditions that give rise to something disappear, everything they’ve been causing also disappears.
A single thought causes my mind to fall into the hell of boiling water, but when that thought is dissolved, this hell also collapses.
This part repeats a couple more times, and it may seem like the meaning is straightforward and doesn’t need repeating, but it’s repeated a number of times in the text. I think it’s because we truly need to grasp this deep down. When we’re stressed, when we’re hurting or overwhelmed, where is our first stop? Where do we look to first? What’s our first, instant thought about how to take care of something? It needs to be our one mind. It’s connected to everything inside and outside, and so can provide energy and/or guidance.
My one mind is the Bodhisattva of Compassion, so I return to my one mind and rely upon it.
