Consciousness is never experienced in the plural, only in the singular. Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world. If I say that there cannot be more than one consciousness in the same mind, this seems a blunt tautology — we are quite unable to imagine the contrary…

Enlightenment by oneself without a teacher (mushi dokugo).
Zen axiom (Zen’s standard for ‘authenticity’)
Do not add legs to a snake.
Zen Proverb (Zen’s version of Ockham’s Razor [Ockham’s Razor is the ‘scientific’ rule or principle which basically asserts that among competing hypotheses the one with the fewest necessary assumptions should be selected; pluralitas non est ponenda sine necessitate, “plurality should not be posited without necessity.” Coined by William of Ockham (c. 1287–1347)]
The classic literature of Zen bristles with assertions insisting that ‘enlightenment’ – the capacity to see the true nature of reality (i.e. dharmas) – is not something that exists ‘objectively,’ like a teaching to learn or discover, or something that exists ‘subjectively,’ like a potential capacity to activate or attain. Enlightenment, the Zen masters assure us, is our birthright; it is and always has been immediately active and accessible here-now (soku) and nowhere else. The refrain in the classic records is so constant as to be nearly continuous; the true nature of dharmas is precisely what is manifesting before your very eyes here-now. ‘Look, look,’ the masters assert, ‘To see is to see true nature; seeing is true nature, true nature is seeing.’ To be (ontology; existence) is to be experienced (epistemology; knowledge), our existence is exactly our experience here-now; our experience is exactly our existence here-now – this (here-now; soku) mind is Buddha.
