Jewish Mysticism
For the emanation is the cause of the revelation of the one who emanates, and thus it also says “he is called by them,” for he has no name or place by which to be called or to be spoken except through his actions, and this is the cause of his revelation. Similarly, this is the cause of his occultation and his concealment so that his divinity will not be revealed except to those who are worthy. There are screens that separate him from the lower entities. This is [the import of the statement that] the disclosure is the cause of the occultation and the occultation the cause of the disclosure (ha-hitgalut sibbat ha-he‘lem we-ha-he‘lem sibbat ha-hitgalut).
