Some witches or black magicians attempt to pull and discourage students from walking the path by making them fall sexually (Yesod).

Some, recognizing we cannot be convinced with amiable means, resort to violence (within Hod, the astral world).
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
