אות - קז

It is known that the study of the Zohar is an immense segulah — very, very great. And know that through the study of the Zohar one develops a longing for all types of Torah study of the Holy Torah. And the holy language of the Zohar greatly arouses one to the service of Hashem Yisburach — namely the praise that it praises and glorifies the servant of Hashem, that is, the language habitually used in the Zohar to say "Zakaa" [praiseworthy] etc., regarding every mitzvah and service. And to the opposite — the cry it cries out: "Vai" etc. and "Vai for him, vai for his soul" (234) — over one who departs from the service of Hashem. These languages greatly arouse a person to His service blessed He. 234. RAK: Part III, 175b.
