Circling from the end to the beginning
1) What Rashi says on Bereishis בְּרֵאשִׁית
(ובשביל ישראל שנקראו (ירמיה ב ג
The last word of the Torah is ישראל
2) -בְּרֵאשִׁית בָּרָא אֱלֹ ים'
The last letters of those 3 words spell out אמֶת = truth (credited to the Ba'al HaTurim) . And the truth of theTorah is made known to us through Moshe having demonstrated it to the eyes of all Israel אֲשֶׁר עָשָׂה משֶׁה לְעֵינֵי כָּל יִשְׂרָאֵל
3) בְּרֵאשִׁית= כָּל יִשְׂרָאֵל
All of Israel = the beginning of everything, for it all depends on the unity of Israel , Only through that do we have standing and the possibility to keep all of the Torah.
