This is taken from Ni's elucidation of the Hua Hu Ching.
I'm thinking of starting and completing all 81 chapters of his book as a study... we did this before but only went through 24 chapters and I'd recommend a read through them.
The background on this topic comes from something I read in his book:
The Constancy of Dao; The Transformation of Life (my paraphrase)
From ch. 38, Ni writes:
"The totality of truth presents itself to you instantaneously every time you blink your eyes. It can dance on the tip of eye lashes. It stretches as far as the eye can see and fills as much as the mind can hold. It exists in every moment of time and every bit of space. Is there any instant which does not contain the truth of life? Is there any place that does not hold the truth of existence and non-existence?"
I shared this with someone who suggested the transformation is the experience of the constancy... but I disagree. the experience of constancy is constancy.
This is more about: form is emptiness and emptiness is form. IMO, Ch. 38 is trying to tell us this.
