According to the wisdom of Kabbalah, a “righteous” person is a person who justifies the Creator, understands the reasons and the essence of his state, and can clearly cut his state into slices of cause and effect.
At the same time he can be in a state of double concealment from the Creator. How is that possible? The whole point is that the concealment and the revelation are determined only by one’s attitude towards the Creator as being “good and benevolent.” It doesn’t matter if I feel good or bad; what’s important is how the Creator is revealed to me. It is important for me to reveal Him as good and benevolent, and not to enjoy His goodness egoistically, because they are two totally different things.
Suppose I have diabetes and you give me a candy. As far as my natural love for sweets goes, it is good. But according to your attitude, it is bad. So it all depends on an internal criterion with which I assess it. What is sweet for the egoism may be bitter if we look at your attitude.
Therefore, to discover the double concealment is to feel all these discernments: I rise above my desire to receive and look at it from the side. Then I see that there is an egoistic intention in it that feels good, while in the desire to bestow, in the intention of in order to bestow, I feel bad. This is the double concealment of the Creator.
