The first word of the Sefer Yetzirah has correspondence with the first word of the Torah.
The word בראשית has a value of 913, the same value that the AvGad of בשלשימ.
The AvGad method of gematria replaces each letter for the next one. This way בשלשימ, with an original value of 682, is converted to גתמתכנ with a value of 913.
The correspondences continue with the first two words of both scriptures. The first two words of the Sefer Yetzirah are בשלשים ושתים. The Mispar Musafi of these words is 1449 and 1449 is the AtBash of בראשית ברא.
