We must work on change of being, but if we work on that as we do everything in ordinary life, life will not be long enough. It is possible to get a durable change of being only if we use the perfected methods of school work, otherwise our attempts will be too scattered. The first condition of such work is not to believe anything, to verify everything one learns; and the second condition is not to do anything unless one understands why and for what purpose one is doing something. So it depends on understanding; all short-cuts depend on understanding
