"...the disciple’s speech should be refined and evolved. Remember how it is said in The Light of Asia that the King, the Self, is within you, and that whatever comes out of your mouth in his presence should be a golden thought expressed in golden words: Govern the lips As they were palace doors, the King within; Tranquil and fair and courteous be all words Which from that presence win."
