And this is the mystery, that the Masters of the Mishnah established:ciBT Berakhot 34b ‘If the prayer is fluent in my mouth, then I know that it is accepted, and if not, then I know that it is torn-up’ – and they tear up his prayer in his face.
And because of this: And it was, before he had finished speaking – and to utter his prayer in the Name of YQV”Q – then immediately, the Shekhinah emerged towards him, [Var. to receive him], and because of him, the Shekhinah descended to his feet. It is this that is written: (Ps. 85:14) Righteousness shall go before him, and shall place his steps ∞pe-’amav upon the way.
