Barchiel--Archangel of Pisces

Bihalami--Angel of the 1'st Deacon of Pisces

Pisces is ruled by the moon. Here is a sigil talisman of
Gabriel, the Archangel of the moon.

A negative aspect in your son's chart is the opposition between Mars and Saturn.
This talisman is designed to overcome the negative influences of that opposition. It
unifies the symbols of Mars and Saturn and gives the names of their Angels
(Cassiel for Saturn and Samal for Mars) in Hebrew.
