A-1 is a level of consciousness immediately adjacent to normal waking consciousness, only one step away from it. Everyone has unconsciously slipped into it at some point.

A-1是紧邻正常醒时意识的一个意识层面，与正常意识仅一步之遥，所有人都曾不自觉滑入其中。

This program treats the Seth Material as a source of hypotheses, not as doctrine to be validated. Lead dossiers are AI-compiled from the corpus with a book-and-session citation after every statement; literature reviews are AI web-search summaries whose references were all DOI-verified against Crossref; the agenda draft is an AI synthesis. None of it is Seth's original text, and none of it represents scientific consensus. English fields are machine-translated; the Chinese text is authoritative.

Adjudicating experiment

First fix the A-1 induction script and experience criteria with an independent pilot sample, then pre-register a multi-center study: approximately 240 ordinary participants and 60 experienced practitioners, randomized order comparing A-1 induction, eyes-open/eyes-closed wakefulness, relaxation, meditation, hypnosis, and polysomnography-confirmed N1; each person undergoes 4–6 visits over 18 months. Record 64–128-channel EEG, EOG, and EMG; pre-register alpha power, source-space connectivity, and coherence metrics with zero-phase contamination removed; approximately 120 additional participants undergo fMRI to compare default mode, salience, and executive networks, with cross-individual and cross-center validation to examine independent neural signatures. In addition, use two-week experience sampling in approximately 1,000 people to estimate spontaneous occurrence rate; a finite sample cannot prove that 'everyone has entered.'
