Berachos discusses the importance of saying shema while wearing tefellin. Saying shema without tefellin is likened to bringing an incomplete sacrifice (Berachos, 14b). Similiary, one who washes his hands, wraps tefellin, says shema, and prays, is likened to building an alter and putting a sacrifice upon it (Berachos, 15b). Since we have the obligation to say shema twice a day (Berachos, 2a), why is it that we do not wrap tefellin in the evening? Where is this discussed?
(Side question: where does one go to get the text to paste in here for quoting text in the Talmud?)
