The prohibition from Above to refrain from open study of the wisdom of truth was for a limited period, until the end of 1490. Thereafter is considered the last generation, in which the prohibition was lifted and permission has been granted to engage in The Book of Zohar. And since the year 1540, it has been a great Mitzva (precept) for the masses to study, old and young. And since the Messiah is bound to come as a result, and for no other reason, it is inappropriate to be negligent.
Abraham Ben Mordechai Azulai, Introduction to the book,
Ohr HaChama [Light of the Sun] 81
For a long time now, my conscience has burdened me with a demand to come out and create a fundamental composition regarding the essence of Judaism, religion, and the wisdom of Kabbalah, and spread it among the nation, so people will come to know and properly understand these exalted matters in their true meaning.
Baal HaSulam, “Time to Act”
Disclosure of the wisdom of the hidden in great masses, which is a necessary precondition that must be met prior to the complete redemption.
Baal HaSulam, “Messiah's Shofar [horn]”
Now you will understand what is written The Zohar: “With this composition, the Children of Israel will be redeemed from exile.” Also, in many other places, only through the expansion of the wisdom of Kabbalah in the masses will we obtain complete redemption. They also said, “The Light in it reforms him.” They were intentionally meticulous about it, to show us that only the Light enclosed within it, “like apples of gold in settings of silver,” in it lies the cure that reforms a person. Both the individual and the nation will not complete the aim for which they were created, except by attaining the internality of the Torah and its secrets.
Baal HaSulam, “Introduction to the Book,
Panim Meirot uMasbirot,” Item 5
It is the great expansion of the wisdom of truth within the nation that we need first, so we may merit receiving the benefit from our Messiah. Consequently, the expansion of the wisdom and the coming of our Messiah are interdependent. Therefore, we must establish seminaries and compose books to hasten the distribution of the wisdom throughout the nation.
Baal HaSulam, “Introduction to the Book,
Panim Meirot uMasbirot,” Item 5
Not only are these secrets not forbidden to disclose, on the contrary, it is a great Mitzva [good deed] to disclose them (as written in Pesachim 119). And one who knows how to disclose and discloses them, his reward is plentiful. This is because on disclosing these Lights to many, particularly to the many, depends the coming of Messiah soon in our days Amen.
Baal HaSulam, “Introduction to The Study
of the Ten Sefirot,” Item 30
It is written that each of the nations will hold a Jewish man and lead him to the Holy Land. And it was not enough that they could leave by themselves. You must understand from where the nations of the world would come by such a will and idea. Know that this is through the dissemination of the true wisdom, so they will evidently see the true God and the true law.
And the dissemination of the wisdom in the masses is called "a Shofar." Like the Shofar, whose voice travels a great distance, the echo of the wisdom will spread all over the world, so even the nations will hear and acknowledge that there is Godly wisdom in Israel.
Baal HaSulam, “Messiah's Shofar [horn]”
The current obligation to expand and consistently engage in the inner side of the Torah, in all its spiritual issues, which broadly include the general wisdom of Israel, whose peak is the knowledge of the Creator in truth, according to the depth of the secrets of Torah, requires clarification, scrutiny, and explanation, to make it increasingly clearer and more ubiquitous among our people.
Rav Raiah Kook,
Otzrot HaRaiah [Treasures of the Raiah], 2, 317
Be strong my friend, shining the Light of the concealed wisdom in the world. Now the days are near when all will know and recognize that the salvation of Israel and the salvation of the entire world depend only on the appearance of the wisdom of the hidden Light of the internality of the secrets of Torah in a clear language.
Rav Raiah Kook, Letters 1, 92
The great spiritual questions, which used to be solved only by the great and the excellent, must now be solved on different degrees for the entire nation, to lower exalted and sublime matters from the height of their tower to the depth of the common and ordinary. This requires tremendous and great richness of spirit along with constant, regular engagement, for only then the mind will expand and the language will be made clearer, to the point of expressing the deeper matters in a light and popular style, to revive thirsty souls.
Rav Raiah Kook, Ikvei Ha'Tzon,
[By the Footsteps of the Flock], 54
The tendency of revealing the secrets of Torah is the ideal goal in life and in reality. The darkness, with which the contents of sanctity are covered, causes man's spirit to diminish, minimizing his aspirations. Thus, he is depleted, the whole of society weakens by the weakening of the individuals, and the nation becomes impoverished of spirit by the draining of its children’s’ spirit.
Rav Raiah Kook, Orot HaKodesh [The Lights of Sanctity] 1, 142
The tenor of life, is to attain adhesion with Him, strictly for the sake of benefitting the Creator, or to reward the public with achieving adhesion with Him.
