What to read after Tikunei Zohar - Rectifications of Splendor - Tome 1 of 5?

Tikunei Zohar, also known as the Tikunim, is a main text of Kabbalah and a separate appendix to the Zohar consisting of seventy commentaries on the opening word of the Torah, "In the beginning (Bereshit)." It contains deep secret mystical teachings, such as the account of Creation through the Hebrew letters, permutations, stirring dialogues, fervent prayers, and the explanation of the Hawayah (Tetragrammaton). The Tikunim, literally Rectifications, are meant to repair and support the Shekinah (Divine Presence), so that we can restore Man from the fallen to the perfect state again. Rabbi Nachman of Breslov was involved with the Tikunim more than with any other book, and he stated that it is of such different holiness and wisdom that it is beyond compare to the rest of the holy Zohar (Chayey Moharan). He also said that "Concerning the book Tikunei Zohar, one thousand books would not suffice to explain the secrets that are to be found there" (Sichot Haran).
