Answer: In the spiritual world, above Bina there is not any clear writing of the black egoism on the white Light.
That doesn’t mean that there are no letters there, just that they cannot be seen on the background of the white Light; they merge with it because a small ego is not revealed in the form of black letters.
In other words, there is only the characteristic of bestowal to Bina. In Talmud Eser Sefirot, in the section about the origin of the human soul, it is said that the letters are derived from a black point (the characteristic of reception), which begins from the center of Bina.
