וְאֵד יַעֲלֶה מִן הָאָרֶץ וְהִשְׁקָה אֶת כָּל וגו' הָאֲדָמָה (ב, ו)
And a mist ascended from the earth and watered the entire… ground. (2:6)
The following story is related in Sefer Degel Machaneh Yehuda:
A man from the city of Boibroka named R’ Efraim Tzitzismacher once spent Shabbos in the court of Rav Avrohom of Stretin zy”a. After Kriyas Hatorah, he felt very hungry and weak. He quickly davened Mussaf b’yechidus, and then went to the place where he was staying, where he made Kiddush and ate the seudah. He then lay down to rest for a little while. Afterwards, he returned to the bais medrash. He arrived just as the Rebbe was sitting down for his tish.
When he opened the door and saw the Rebbe sitting by the table, with all the chasidim surrounding him, he greatly regretted what he had done. He felt terrible that he had missed davening Mussaf with the Rebbe and hearing his “Keser”, which was known to be especially powerful and inspiring. These thoughts pervaded his mind as he walked towards the table.
The Rebbe sensed his thoughts and said, “It is stated that a mist (v’eid) descended upon the earth (ha’aretz) and watered the entire ground. The word ‘v’eid’ can also mean ‘broken’, while the word ‘aretz’ symbolizes physical matters (artzius). Thus, the pasuk is saying that if a person’s heart is broken because he engaged in physical matters like eating, the power of this broken heart can ‘water the entire ground’, meaning that it can provide good influences to the entire world.”
