Experimenting with your life
The genuine followers of the perennial philosophy shall remain few, not because it requires great understanding, but because the following of that philosophy requires so great a moral courage and unflagging determination. The philosophy of mysticism, unlike some others, is not dependent upon intellect for confirmation, but upon experiment. It remains incomprehensible to all but those who are willing to carry out the experiment with their very lives.
