God also created Saturday, Thursday, Tuesday, Sunday, Friday, Wednesday, and Monday with these seven double letters. God also created seven gates to the soul. These are the two eyes, two ears, two nostrils, and the mouth. The twelve simple letters are Heh, Vau, Zayin, Cheth, Teth, Yod, Lamed, Nun, Samekh, Ayin, Tzaddi, and Qoph. From them, God created the Zodiac and the twelve months.
Kabbalists group the simple letters into four triplets.
Three of the letters radiate love. Three emanate hate. Three engender life, and three bring death. Each letter also corresponds to an English letter. Finally, each letter of the Hebrew alphabet has numerical value.
