The Baal HaTurim writes that the last letters of 6 different three word groups in the first few pasuchs of Bereishis spell "Emes". And it is for this reason that we say "Emes" 6 times after the "Shma". That is of course, if you daven Ashkenaz. Nusach Sefard says the word "emes" 8 times.[This was gleaned from the Artscroll edition of The Baal HaTurim] And the Heichel HaBaroche, the first Kamarno Rebbe writes in his siddur, after Shma, "Be sure to say "emes" 8 times." I asked different people (forgive me I didn't ask you Reb Simcha) why were there 8 instead of 6. No one gave me an answer. I took it on myself to count the word "Emes" in the Sefard siddur. It was said 15 times, from morning brachas to Aleinu. It struck me that one of these 15 was smack in the middle of pesuke dezemer. To be sure I counted words.It was close but what came out of this inquiry was amazing!! From the word after this particular "emes" until the end of psalm 150, including the repetition of Kol haNeshama Tahalal Kah Halleuka, was 368 words. 368 is the gematria of "Ani Eved HaShem, Ain Ode Milvado" Don't serve your Master as a slave expecting a reward, be like servants who serve their Master not for the sake of receiving a reward (with 15 expressions of Praise)
