Mysteries Not to be Discussed
He made no secret of the fact that the Kabbalah was the positive ground on which he stood in his struggle against rationalist enlightenment. He derided the Maimonideans in witty verses in which he sought to expose the weaknesses of their position. But the kabbalistic doctrines themselves, which he manifestly opposes to them, are only for initiates who weigh their words and know how to keep silent. He had studied the secret science with Ezra and Azriel:
Yes, my supports are Ezra and Azriel, who pour kabbaloth onto my hands.”
In a panegyric to the members of his circle he bemoans the death of the two “whose shields hang upon my walls.” He stands on solid ground:
The ‘ephod is in our midst; and why should we conjure the dead; in our hands the tablets are intact. The son of Nahman is a firm refuge, his discourses are measured and do not gallop away recklessly. Ezra and Azriel and my other friends, who taught me knowledge without lying—they are my priests, the luminous stars of my night. They know number and measure for their Creator, but they guard themselves from speaking publicly of God’s glory and they mind their words with a view to the heretics.
His masters in mysticism taught him to keep silent; nevertheless, he mentions the mystical kawwanah of the prayers, the meditation in the profession of unity, the mystical reasons for precisely those commandments that were emphasized by the kabbalists of Gerona, and he alludes to the doctrine of the sefiroth.
Like Jacob ben Shesheth, he reproaches the rationalists for no longer knowing how to pray, and he defends the mystical character of those aggadoth that embarrassed them the most:
Softly—you who find fault with the aggadoth! Perhaps they are mysteries, not to be discussed.
