All things have no signs:
This is the real body of Buddha.Avatamsaka Sutra (Cleary 1984, 380)
All thought is in signs.Peirce (EP1:24)
From Dogen's Fukanzazengi (‘Instructions for Zazen’):
Put aside all involvements and suspend all affairs. Do not think good or bad. Do not judge true or false. Give up the operations of mind, intellect, and consciousness; stop measuring with thoughts, ideas, and views. Have no designs on becoming a Buddha.
Could it be that the real body of Buddha is what Dogen called One Bright Pearl?
and what Peirce called the phaneron? He used this word ‘to denote the total content of any one consciousness (for any one is substantially any other), the sum of all we have in mind in any way whatever, regardless of its cognitive value’ (EP2:362).
Can this question be investigated?
The investigator would have to practice both phaneroscopy and zazen,
and be fluent in both Peircean and Buddhist dialects.
Is it possible to investigate such a question while practicing
zazen or phaneroscopy?
This question is left as an exercise for the reader (along with the links provided here).
