Is the Sepher Yetsira a reliable reading source ? The Sepher Yetsira is one of the main cabalistic books of today, because it describes some characteristics of each of the Hebrew letters and talks about their elemental, zodiac and planetary position, but reading it I wanted to know if it is a reliable source, because I am trying to study the Greek letters (from where most of the Hebrew letters were stolen), and as the characteristics of the stolen letters are similar I would like to know if it is reliable to use it to get an idea of the characteristics of the Greek letters.
Another question I have about the Greek letters is why some ancient letters were taken from the Greek alphabet ?
If Hodedcobra or any advanced member can answer I would appreciate it.
