Adam was away from his wife for 130 years. During this time, he coupled with females from the negative side. As a result, they brought to the world impure spirits, like demons. They are called ‘נִגְעֵי בְּנֵי אָדָם.’, ‘plague of humans’. They are another aspect of negativity that is inflicted by the Snake.
When a person goes to sleep, his soul leaves the body that stays without control of itself. When in sleep state, the impure spirits can come around a person and ‘play’ with the soul and body. Sometimes, a man may be ‘visited’ by impure female entities that come to draw and connect to his sexual desires. They get impregnated from him and deliver impure spirits that some of them look like humans but without hair on their heads.
We should avoid connection with these impure spirits. We can do so by following the ways of the Torah. During sleep, we experience the aspect of death because only one part of 60 parts of the soul stays with the body to sustain its connection to life. The body gets impure during the night and when we wake up in the morning, we should not touch ourselves, especially the eyes, before proper washing of the hands from the impure spirits.
The root word ‘נגע’, ‘plague’, also means ‘touch’, ‘connection’. The same word is used in the Torah with connection to leprosy (Leviticus 13:9), “נֶגַע צָרַעַת כִּי תִהְיֶה בְּאָדָם”, “When the infection (נֶגַע) of leprosy is on a man, then he shall be brought to the priest”.
As we studied here, ‘נגע’ it’s a connection to negativity.
When we rearrange the same letters as ‘ענג’, we get the meaning of ‘pleasure’. This word is used to describe the pleasure of the Shabbat when we can close and touch/connect to the Light of YHVH.
“וְקָרָאתָ לַשַּׁבָּת עֹנֶג לִקְדוֹשׁ יְהוָה מְכֻבָּד”
“And call the Sabbath a delight (עֹנֶג, Pleasure), for the honor of the holy YHVH”.
To protect ourselves from the negative entities at night we use the Bedtime Shema that uses several aspects of the number 60 to protect our soul and body from negative entities. Any spiritual connection at night would benefit us with a night of good and protected sleep.
