In a letter written by the Baal Shem Tov to his brother-in-law, Rabbi Gershon of Kitov, it states: "I asked my Master and teacher to go with me, for it is exceedingly dangerous to ascend to the highest of the upper worlds and since that time I arrived at my present spiritual level, I had ascended to such places.
I went up, level after level, until I entered the palace of Moshiach, where he studies Torah with all the Tannaim and the Tzaddikim, and with the Seven Shepherds. I beheld very great joy there, but I did not know the reason for this extreme happiness.
I thought this joy was, G*d forbid, because of my demise from this world. But they told me later that I was not deceased and that they derived tremendous pleasure when I performed yichudim in the physical world by means of the Torah. But as to the meaning of this great rejoicing, I still do not know.
And I asked Moshiach, 'When are you coming, my Master?'
He answered me, 'By this you shall know it: Once your teachings become publicly known and revealed throughout the world; when your wellsprings have overflowed beyond, imparting to others what I have taught you and you have grasped; so that they too will be able to perform yichudim and Aliyahs of the Neshama as you do. Then all the kelipos will perish, and it will be a time of favor and salvation."
I was bewildered at this response. I felt great anguish because of the length of time that Moshiach implied it would take until he came.
However while I was there, I learned three Segulos and three Holy Names which were easy to learn and to explain to others and which would allow them to perform yichudim and Aliyahs of the Neshama. So I felt reassured, and I thought that perhaps, using these Segulos and Holy Names, my Chavurah, might also be able to attain my spiritual level. That is, they would be able to practice Ascents of the Soul, and learn and understand the Supernal Mysteries as I do.
But I was not permitted and I am under oath not to reveal them during my life."
