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 everyone can attain to his 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.
