אות-לט

The essential rectification of the diminishment of the moon is through strengthening that comes through joy — in the aspect of: "for the joy of Hashem is your strength". And this is why Hashem warned Yehoshua many times: "Be strong and courageous" — for Yehoshua is in the aspect of the moon, as our sages of blessed memory said. (ibid., Ois 49)
