As he says, the revelation of this book, as well as the fact that he was able to create a commentary on the entire Book of Zohar is a sign that the generation is already worthy of correction, the revelation of spirituality to the masses, and with the dissemination of The Book of Zohar the whole world will come closer to correction.
When Baal HaSulam published The Zohar with the Sulam Commentary, his students walked around the streets carrying volumes of this book, going to different places in an attempt to disseminate it. It was very difficult. People were afraid of The Book of Zohar because there were rumors that this book is very special, that is has enormous power, and is able to bring benefit as well as harm.
Only in our time, 60 or 70 years after the Sulam Commentary was created, we are presenting The Zohar to the world in an adapted form that makes it accessible for the wide masses so that everyone could read it and enjoy it.
