On this journey certain coins are necessary also, to spend on the way. And what are these coins? They are thoughtful expressions in word and in action. On this journey man must take provision to eat and drink, and that provision is life and light. And on this journey man has to take something in which to clothe himself against wind, and storm, and heat, and cold; and that garment is the vow of secrecy, the tendency to silence. On this journey man has to bid farewell to others when starting, and that farewell is loving detachment; before starting on this journey he has to leave something behind with his friends, and that is happy memories of the past.
