All the religions of the past have made use of this truth. It has been a cult in every religion, but they have only given the outcome to the world without making its mystery known. The great mystics who understood it did not impart this knowledge to the masses. It would not be wise to give a loaded revolver to a person who may lose his temper at any moment; it is necessary to be sure that he has such control that he will only use it in the best way. So it has been with the mystics. They do not give initiation until they are sure that they can trust a person, that he will make the best use of it. It is not that they are afraid of somebody stealing the mastery they possess; if it were only that, the mystic would be no different from any worldly man who is clinging to his possessions. The mystic must be more generous with his knowledge than anyone else. He is aware that anyone can attain to this knowledge, and he must always help others. Out of the goodness and kindness of his heart he will deny no one his help in every possible way.
