When Pinchas saw Balaam disappearing in the air, he called his armies to find who can fly after Balaam.
Tzalya, from the tribe of Dan, connected to the force that controls magic and flew after Balaam. When Balaam saw that he’s being chased, he made special manoeuvres to breakthrough levels in the sky and disappeared. Tzalya didn’t know what to do and was sad.
Pinchas raised his voice and gave Tzalya advice using code words “The shadow of the crocodiles that are scattered on all the snakes, look in your hair”. Tzalya understood the message immediately, he found the path to Balaam and made him come down together in front of Pinchas.
The name Tzalya, ‘צל יה’, means ‘shadow of YH’ that has the aspect of the centre column of holiness. The witchcraft and magic are on the Left and Tzalya could take control over it and chase Balaam. Balaam had a high-level spiritual connection on the other-side and manoeuvred to the upper three Sefirot of the Left and disappeared from Tzalya. That made Tzalya sad because he feared to go after him, an action that would make him lose his connection to holiness.
When Tzalya understood the message from Pinchas, he connected to the point (hair that is energy from the head, upper three sefirot). With that connection, he cancelled the magic (the aspect of snakes) that Balaam used to go into the upper three sefirot of the Left. By cancelling the path Balaam took, Tzalya forced him to disconnect from his upper three connection and drop down to Malchut together with him.
In earlier time periods, the forces of the spiritual realms were strong on the pure and impure side. The energy of the negative side was easy to connect to. But the pure side could always cancel the existence of any negative force, even if it’s not visible to us.
