The “one weird trick” to getting the right answers is to discard all stuck, fixed points. Discard all priors and posteriors. Discard all aliefs and beliefs. Discard worldview after worldview. Discard perspective. Discard unity. Discard separation. Discard conceptuality. Discard map, discard territory. Discard past, present, and future. Discard a sense of you. Discard a sense of world. Discard dichotomy and trichotomy. Discard vague senses of wishy-washy flip floppiness. Discard something vs nothing. Discard one vs all. Discard symbols, discard signs, discard waves, discard particles.
All of these things are Ignorance. Discard Ignorance.
Is this the same principle as “non-attachment”?
Yes non-attachment points in the same direction.
Another way of putting it is “negate everything.”
Another way of putting it is “say yes to everything.”
Both of these work toward non-attachment.
