Likutei Moharan, Part II 82:2/ליקוטי מוהר"ן·תנינא פ״ב:ב׳

12. Now, the concept of order is called yod. Malkhut, which is called Dalet, has nothing of Her own. The Blessed Holy One draws into Her the life-force of wisdom, which is called YOD, namely Yod Vav Dalet. This is also “Back and front You formed me, and You laid kapekha (Your palm) upon me”—do not read KaPekha but KaPhekha (Your [letter] kaph). This alludes to YOD, whose numerical value is kaph. But when one splits off the Dalet for himself, drawing life-force from Her to himself, things then become chaotic for him, davoy—YOD becomes DaVoY. This is “and every heart is davoy (sick)” (Isaiah 1:5), for when things don’t go as planned, that is heartache, as it is written, “Extended longing…” (Proverbs 13:12).

2Thus, when a person sees within himself that things aren’t going for him as planned, he should know that he possesses haughtiness—i.e., “I will rule.” He should repent and humble himself, and be the concept of MaH, as it is written, “And we are MaH (what)” (Exodus 16:7). Then Chavah is restored to the concept of Adam/ MaH and becomes order, that is, “Back and front….”—i.e., KaPekha, namely, YOD .
