The Torah is stamped with Emes with the words brehsiT baraH ElokiM(last letters of each word)and later emes is spelled out in order by the end of parsha of creation baraH ElokiM lasoT.The lesson is that Emes is only achieved through effort and doesn’t come instantaneously(Arzei Levanon).The Ibn Ezra explains that the Torah is stamped with emes based on the fact the Torah starts with a bais and not an aleph. This idea is conveyed through Mispar Kattan(digit-sum) mispar kattan of emes is 441 and 4+4+1 =9 and mipar kattan of sheker is 600 and 6+0+0=6.If one starts with bais and groups letters in threes the mipar kattan of each group of three will be 9,and if it started with aleph then each group would equal 6(e.g bais + gimmil + daled= 9,and aleph + bais + gimmil= 6)From here we see the essence of the Torah is Emes.
