Baal HaSulam made it so that if an ordinary person were to walk in his path, he would be able to discover the Creator.
Rav Baruch Ashlag, “The Works of the Greatest in the Nation”
When Baal HaSulam began to publish his writings, he was greeted with enthusiasm by the spiritual leaders of his time:
A Godly sage of great understanding has come, a sacred treasure ... and the spirit of the Lord was upon him to compose the sacred book ... to the truth of the Torah and in true foundations ... happy is the woman who bore him.
The Rav Kook
The great priest of the study of Kabbalah, whose name is renowned.
Rav Yosef Chaim Zonenfeld
How glorified is the day when the bright light has appeared before us, the Sulam commentary on the Holy Zohar ... and with the hand of the Lord upon him, the great Kabbalist ... the minister of the house of Zohar.
Rav Yaakov Moshe HARLAP
He illuminated the eyes of sages with the words of the Holy Zohar ... which is a ladder placed on the earth, and its top reaches the heaven.
Rav Ben-Zion Meir Hai Uziel
It was possible to obtain The Book of Zohar even before Baal HaSulam wrote the Sulam commentary, but people did not understand what it said. The role of The Book of Zohar as a means to reveal the Creator is the thing that was hidden, and that is now revealed. The Sulam commentary opens before us the ability to correct ourselves and to discover the Creator. This is why Baal HaSulam disclosed The Zohar. And because he concluded thousands of years of concealment of The Book of Zohar, these and other acknowledgements35 soon appeared.
The following words, which were found among his writings, give us a clue into the spiritual level of Baal HaSulam:
And God said unto me: “Get thee out of thy country, [1] to the pleasant land, the land of the Holy Fathers, where I will make you a great sage and all the sages of the land shall be blessed in you, for I have chosen you for a righteous sage in all this generation, to heal the human suffering with lasting salvation.”
Baal HaSulam, “The Prophecy of Baal HaSulam”
And by a Higher Will, I have been awarded the impregnation of the soul of the Ari ... and I cannot elaborate on this matter, as it is not my way to speak of the incomprehensible.
