Answer: A “secret” is something I cannot reveal even though it’s clear to me that it exists. I experience the sensation of a “secret” when standing at the threshold of something new, before opening up the door.
Besides, irrelative of me, “secrets of the Torah” are the Lights that are concealed by Atik. They are in the head of Arich Anpin in the form of a concealed wisdom. These Lights are hidden because right now we do not have a covering for them which would enable us to discern them. However, for me they are not a secret because I do not feel them.
The real secret is the curtain that I feel. For example, exile is the anticipation of redemption, which is felt as extremely necessary but not yet acquired. Inside the very sensation of the emptiness, I already outline the contours of the future fulfillment. This means experiencing oneself in exile: I understand and feel what I want, and all I lack is the implementation.
The same is true for a “secret”: I feel that I lack the quality of bestowal so that inside of its Light of Hassadim I would reveal the Light of Hochma. The knowledge that brings this Light is hidden from me.
