Likutei Moharan, Part II 88:2/ליקוטי מוהר"ן·תנינא פ״ח:ב׳

12. Know, too, there is an angel with many deputies, all of them holding shofars. Standing and digging constantly, always searching for lost things, they blow a tekiah, a teruah, and then again blow a tekiah. And when they find something which was lost, it creates great tumult and joy.

2For there are many lost things—i.e., the many things which people lose as a result of desires, as in “The desire of the wicked shall be loss” (Psalms 112:10).

3Even someone who is a tzaddik also occasionally loses, as in “There is a tzaddik who loses through his righteousness” (Ecclesiastes 7:15). And even the tzaddikim who search for and seek out lost things also occasionally lose, as in “they will search and lose” (Psalms 83:18) that even those who search for lost things occasionally lose in turn, this being the concept of “a time to lose” (Ecclesiastes 3:6).

4And this is “Taavat Resha’im Toveid (The desire of the wicked shall be loss),” the initial letters of which stand for Tekiah teRuah Tekiah. The angels who look for lost things—they being the concept of Taavat Resha’im Toveid—hold shofars in their hands and blow TaRaT (tekiah teruah tekiah), as mentioned above.

5He also mentioned then that it is extremely difficult to be a receiver. And he also mentioned then that jealousy between scholars increases wisdom (Bava Batra 21a). Yet he did not clarify any of this, for they are inscrutable and sealed matters. Moreover, some of it has been forgotten, because I did not record them at the time, except as brief notes (as printed in the first edition).

6And he said that all the aforementioned—i.e., the Kabbalistic meditations for Elul, which are a rectification for a blemish of the brit—and the above teaching concerning the fruit, and this teaching about the angel, etc.—are all one [idea]. This involves deep mysteries.
