Midrash Rabbah Devarim on the Meticulousness in the Enunciation of the Letters of the Recitation of the Shema

"A halakhic question: A man of Israel who recited the Shema reading and was not meticulous in enunciating each of its letters, has he fulfilled his obligation?

"The Sages taught in a Mishnah: If one recited the Shema and was not meticulous in enunciating each of its letters, Rabbi Yose says that he fulfilled his obligation, but Rabbi Yehudah says that he has not fulfilled his obligation.

"And what is 'meticulousness of the letters'? Our Rabbis taught us: With regard to the words 'bechol' and 'levavchem' (Deut. 11:13), one must separate between the lamed at end of bechold and the lamed at the beginning of levavchem. Similarly with regard to the words 'vaavadtem' and 'meheirah' (Deut. 11:17), one must separate between the mem at the end of 'vaavadtem' and the mem at the beginning of 'meheirah'."

-- Midrash Rabbah, Devarim Rabbah, 2.31


This is a very straightforward proof-text for the fact that halakhic regulations are expressed as morphic functions of the vibrational effect generated by the person's actions in the world. That is, there is a mathematical physics to halakhah, in addition to the scholarly dimension of Talmudic analysis.

Here, the fulfillment of the Shema is a function of the correct pronunciation of each letter that comprises each of the 248 words that make up the daily Shema recitation.
