“The nakedness of thy father and the nakedness of thy mother shalt thou not uncover,” refers to the prohibition of receiving the direct Light from the spiritual system of AVI (Aba ve Ima – Father and Mother). The Light that constantly descends from above is only in clothing that matches it.
In our world, for example, I can transmit a certain frequency over a great distance, but in empty space, my transmission only can spread out a distance of a kilometer or so.
If I wish to transmit sound to a distance of five hundred kilometers, or in space, I must increase the ordinary frequency by dressing it in a higher frequency. When one frequency rides on another, I perform modulation, and then the signal is transmitted smoothly.
In other words, the frequency of sound rides on the greater frequency of my generator. Thus, I thus transmit the sound. At the same time, the form of my sound is on a high frequency, and the transmitter that transmits it through a filter removes it, thus leaving only the voice frequency that enters the loudspeaker, through which the sound is heard.
Thus, the sound from the transmitter to the receiver is on high frequency and undergoes modulation and filtering. This is fulfilled according to the model of the passage of the Upper Light. The physical laws in our world are a result of the attributes of the Upper Light. If we wish to transmit something a great distance, we always transmit it through some environment or by riding a higher frequency.
It is the same in the spiritual world. If there is a signal from below, it must be dressed in some other Light, another frequency. The clothing is the Light of Hassadim, the Light of Hesed, the Light of bestowal that must come from the source to the receiver. The receiver must have the opposite attribute in order to receive this attribute and to separate the inner attribute of bestowal from the actual receiving.
The bestowal that descends from the system of Father and from the system of Mother (the Light of Hochma and the Light of Hassadim) is always dressed in such clothing. When they descend, we can connect them only in blocks that are similar to one another. Therefore, there is the restriction of “the nakedness of thy father…shalt thou not uncover,” which means that it is forbidden to uncover the Light of Hochma that is not dressed in the Light of Hassadim.
