`Out of nowhere, the mind comes forth'I rediscovered this a few minutes ago... and I suddenly realized that it describes not only the essence/nature of meditation, but the essence/root of mathematical discovery as well.
The Diamond Sutra
Mind, matter, universe appear to be grounded in this 'nowhere'/emptiness (often seen as `beginning', but that may not be the case) in that every meditation, every mathematical discovery recreates the otherwise elusive `coming forth', leaving one absolutely surprised by this Planck-scale illumination.
