If there is such a thing as“the fabric of reality”, perhaps it is so painfully obvious that we overlook it. Consider these criteria: it must be the same now as it always was, hence it is nothing new; it must be everywhere, hence microscopes and telescopes get us no closer; it must be inherent in everything, hence favouring certain things does not help; it must encompass both subject and object, hence apparent separateness must be dissolved.
Bare witnessing fits these criteria. The mere fact of experiencing. Just this.
