The Embodiment of Tau

"THE tau (reason) which can be tau-ed (reasoned) is not the Eternal Tau (Reason). The name which can be named is not the Eternal Name. Non-existence is named the Antecedent of heaven and earth; and Existence is named the Mother of all things. In eternal non-existence, therefore, man seeks to pierce the primordial mystery; and, in eternal existence, to behold the issues of the Universe. But these two are one and the same, and differ only in name. This sameness (of existence and non-existence) I call the abyss - the abyss of abysses - the gate of all mystery."
