For the Source Temple, I had to use a game guide or two in English. And at least one in German! Being from Denmark, I can read German. However, I found the Source Temple to be very frustrating.
Especially, the hatch puzzle at the end of the temple...
Also, you sometimes need to open a door via a hidden button. You'll need to have a perception of at least 14 or 15 before the button reveals itself. At a certain point in the hatch puzzle, you also need a rather high perception to reveal this hidden button. I somehow must have the info on this.
