The Zohar as a Means to Discover the Creator
Know that the entire Book of Zohar and the obligation to study it etc., is all a positive Mitzva [commandment to do a certain action], to cleave to it and to know that God is found, in sacred knowledge in the particular and in the unifications, and with love, fear, and unity.
Rav Yitzhak Yehuda Yehiel Safrin of Komarno,
Netiv Mitzvotecha [The Path of Your Commandments], Path 2, Item 3
Hear me my brothers and companions, the friends, who are craving and seeking the truth, the truth of the work of the heart—to behold the pleasantness of the Creator and to visit His Hall: My soul shall bend and cling unto The Book of Zohar, as the power of engaging in the holy book is known from our ancient sages.
Rabbi Tzvi Hirsh Eichenstein of Ziditshov,
Sur MeRa [Depart from Evil], p 4
It is known that the study of The Zohar is capable indeed. Know that the study of The Zohar creates desire, and the holy words of The Zohar strongly evoke to the work of God.
Rabbi Nachman of Breslev,
Talks of Rabbi Nachman, 108
The merit of one who contemplates the words of the living God, The Book of Zohar and all that accompany it, the words of the sages of truth, and the writings of the Ari is immeasurable. Through the constant engagement, they will discover the gates of light and the doors of wisdom for all who sincerely follow the path of God, whose soul desires to approach the palace of the King of Honor who lives forever, blessed be He. Hence, all who volunteer to engage in the wisdom for even an hour or two a day, each day ... and the Creator adds a good thought to an action. It will be considered as though he stands all day always in the courts of the Lord, and his dwellings are in the secrets of the Torah.
The Rav Raiah Kook,
Letters of the Raiah, Part One, p 85
One who studies The Zohar, which is the wisdom of Kabbalah, becomes a son to the Creator.
Zohar, Livorno, publisher’s introduction
Let every son of Israel grow strong in the holy Zohar, even if he shall undergo several attempts to separate him from studying the holy Zohar. Also, if he has been through several attempts by people who are materialized in their substance, who are the harlequins of the generation, and he sits among them as a lily among the thorns...
Let one who has a soul of Israel, who wishes to cleave adherently to the Creator ... although at times it seems to him that he is as a lily among thorns, let him pay no heed to that. Let us be strong and grow stronger in the power of the Ein Sof blessed be He and blessed be His name.
Rabbi Eliezer Bar Yitzhak Pappo, (Eliezer of Damascus),
Introduction, Path of Holiness, Item 12
