Likutei Moharan, Part II 2:8/ליקוטי מוהר"ן·תנינא ב׳:ח׳

18. And this is the meaning of: “And it happened at the end of two years of days” (Genesis 41:1).

2at the end of— This refers to “the end.” It alludes to halakhot, the delight of the World to Come, which is at the end.

3And this is: two years of days— As in the teaching of our Sages, of blessed memory, concerning that “one day yeshiva student.” He was dejected until Rabbi Yochanan applied to him the following exposition: “Yet Me they seek day, day” (Isaiah 58:2)—one day of the year is considered an entire year (Chagigah 5b). This is the meaning of “two years’ of days.” Study of halakhot causes the days to be reckoned as years, as in “they seek day, day.” {We did not merit hearing the completion of the exposition of this verse based on the above lesson.}
