The Guru Also Says:

As the Holy War proceeds we are somewhat surprised that no one has brought up the parallel afforded by "the Old Man of the Mountain," one Hassan ben Saba, who during the Crusades created a Muslim paradise into which he introduced recruits in order to prove to them that if they died carrying out his orders eternal paradise would be theirs. He made liberal use of the drug hashish and thus gave his name to the term "assassin." The suicidal assassin does indeed pose a special problem, but problems are made to be solved.
