Ba'al Shem Tov, Noach 19/בעל שם טוב על התורה·נח י״ט

1I heard in the name of the Baal Shem Tov of blessed memory, that he explained the verse (Genesis 16:6) "Make an opening for the ark (teivah)" - one should turn the words (teivah) of Torah and of prayer into an illuminated opening, to look and see from the beginning of the world until its end.
