Abraham Gershon of Kitov, also known as Rabbi Gershon of Brody, was probably born in or near Kuty (Kitov), Poland around 1701 and died in Jerusalem in 1761. He is best known as the Baal Shem Tov's brother-in-law.
Brother-in-law of the Baal Shem Tov.
According to tradition, the Secret Society of Kabbalists started teaching the Baal Shem Tov the path of the Mystics, at the age of 14. When 18 years of age, the Baal Shem Tov already attained a significant role in the Secret Society, though outwardly, he remained the simple caretaker of the local synagogue. He moved from Okap to Brody, where he lived as a teacher of young children. There, the Baal Shem Tov married the daughter of Rabbi Ephraim of Brody, though to the dismay of Rabbi Ephriam's son, Gershon of Kitov, who considered the hidden Tzaddik an ignorant person, as he might have appeared, on the surface.
The Disappearing Brother-in-law
"I have sought my brother-in-law, Reb Gershon, in Eretz Yisrael, but he is not there," exclaimed the Baal Shem Tov in puzzlement on Friday evening as he sat in his beit midrash in Mezibuz. But on the following day, during the services, he declared that he now saw him in Eretz Yisrael.
Many years later he had occasion to meet his brother-in-law and question him concerning that Shabbat. Reb Gershon knotted his brows, trying hard to recollect where he had been on that Shabbat many years ago. "I remember now," he exclaimed. "I was honored with a brit milah in the city of Acco, which had two synagogues. On Friday evening I prayed in the one that is considered outside the boundary of the Holy Land but on the morrow, after I had discovered my error, I prayed in the other synagogue. (Shivchei HaBaal Shem Tov)
A letter by Rabbi Yisrael, The Baal Shem Tov to his brother in-law, Rabbi Gershon of Kitov
To my beloved brother-in-law, my friend who is dear to me as my own heart and soul, the exalted rabbi and Chasid, renowned for his Torah scholarship and fear of Heaven, our master, Rabbi Avraham Gershon, may his light shine. Peace unto him and his family, his modest wife, Bluma, together with all their children; may they be blessed with life, amen, sela...
I received the letter written by your holy hand, which you sent by means of the emissary from Jerusalem, at the fair of Luka in the year 5510 (1750 c.e.). It was written with extreme brevity, explaining that you had already written at length to each of us individually and had sent those letters by means of a certain man en route to Egypt. However, the letters never arrived, and I was sorely grieved that I never saw the work of your holy hand which was written in greater detail. Assuredly this is due to the calamitous state of the many lands in which the plague has spread because of our many transgressions. Not far from our region the pestilence has reached the holy community of Mohilev, as well as Wallachia and Turkey.
[Your letter] also states that the Torah teachings and mystical revelations which I sent you through the rabbi and preacher of the holy community of Polonoye did not reach you; this, too, caused me great distress. It certainly would have given you great joy if they had reached you. I have since forgotten many [of those teachings]. However, the few details I still remember I will write to you in brief.
On Rosh Hashanah of the year 5507 (1746 cue.), I made a [Kabbalistic] oath and elevated my soul in the manner known to you. I saw wondrous things in a vision, the like of which I had never witnessed since the day my mind first began to awaken. The things which I saw and learned when I ascended there would be impossible to communicate, even if I could speak to you in person. When I returned to the lower Garden of Eden, I saw many souls, both living and dead, some known to me and others unknown-their number was beyond reckoning. They were hastening to and from in order to ascend from one world to another through the Column known to those initiated into the Mysteries. Their joy was too great for the mouth to express or the physical ear to hear. Also, many evil-doers were repenting, and their sins were being forgiven, since it was a special time of Divine favor. Even to me, it was amazing how many of them were accepted as penitents, a number of whom you also know. There was great joy among them, too, and they ascended in he same manner.
Together they begged and implored me unceasingly, "Because of the glory of your Torah, God has granted you an additional measure of understanding to grasp and to know these matters. Ascend with us so that you can be our help and support."
Because of the great joy that I beheld among them, I agreed to go up with them... And I besought my master (Achiyah HaShiloni) to accompany me, for the ascent to the Supernal Worlds is fraught with danger. From the day of my birth until now, I never experienced such an ascent as this.
I went up from level to level until I entered the Palace of Mashiach, where Mashiach studies with the Tannaim and tzaddikim, as well as the Seven Shepherds. There I found extremely great rejoicing, but I did not know the cause of this delight. At first I thought that it might be due to my having passed away from the physical world, God forbid. Later they told me that I had not yet died, for they have great pleasure on high when I effect mystical unifications in the world below through their holy Torah. However, to this very day, the nature of their joy remains unknown to me.
I asked Mashiach, "When will you come, master?" And he replied, "By this you shall know: it will be a time when your teachings become publicized and revealed to the world, and your well-springs have overflowed to the outside. [It will be when] that which I have taught you-and that which you have perceived of your own efforts-become known, so that others, too, will be able to perform mystical unifications and ascents of the soul like you. Then all the evil klippot(husks) will be destroyed, and it will be a time of grace and salvation."
I was amazed at this and greatly troubled, since a long time must pass for this to be possible. But while I was there I learned three segulot (spiritual remedies) and three Holy Names which are easy to learn and explain. My mind was then set at ease, and I thought that with these teachings the people of my own generation might attain the same spiritual level and state as myself. They would be able to elevate their souls and to learn and perceive just as I do. However, I was not granted permission to reveal this during my lifetime. I pleaded for your sake to be allowed to teach you; but I was denied permission altogether and took an oath to that effect.
Yet this I can tell you, and may God assist you, that your way may pleasant to the Lord, and that you do not go astray (particularly in the Holy Land). Whenever you pray or study-and with every utterance your lips-intend to bring about the unification of a Divine Name. For every letter contains worlds and souls and Godliness, and they ascend and combine and unite with one another. Then the letters combine and unite to form a word, and they are actually unified with the Divine essence-and in all these aspects, your soul is bound up with them. All the worlds become unified as one, and they ascend and bring about great joy and delight without measure. Consider the joy of a bridegroom and bride in this lowly physical world, and you will realize how much greater is the joy on such a lofty spiritual level.
God will surely help you. Wherever you turn, you will succeed and become enlightened. "Give wisdom to the wise, and he will become wise all the more." Please pray for my sake, that I might be privileged to dwell in God's land during my lifetime; and pray for the remnant of our people who still remain in the Diaspora.
These are the words of your brother-in-law who longs to see you face-to-face, who prays that length of days be granted to you and your wife and children, and who wishes you peace "all your days-including the nights, for many good years, amen, sela.

May the merit of the tzaddik Rabbi Avraham Gershon of Kitov protect us all, Amen.
