A man's inner experience may reach far and yet be commingled with a character only partially purified. His mystical attainment may or may not confer a total transformation of his nature, a total subjugation of its lower part to the higher--that depends on Grace. This explains the moral weaknesses of some mystics who have given us great teachings. Only the very few who have taken the pains to undergo a thorough re-education of their whole being, and to bring it into proper equilibrium, involving its development and its discipline, are likely to receive the Grace which will make them morally faultless as well as scrupulous practitioners of their own preachment.
