“Knowledge is something which you can use.Belief is something which uses you.”

“One can give or withhold in a manner far more effective, sophisticated, useful, which is quite invisible to people who think that giving or withholding is done by external assessment. If you seek some mark of favour or 'promotion', know that you are not ready for it. Progress comes through capacity to learn, and is irresistible. Nobody can stand between you and knowledge if you are fit for it.”

“A real secret is something which only one person knows.”

“Opinion is usually something which people have when they lack comprehensive information.”

“Learn to be as analytical about things of which you are credulous as you are of those which you criticise.”

“The sufis believe that they can experience something more complete.”

“The more you look at 'common knowledge', the more you realise that it is more likely to be common than it is to be knowledge.No real knowledge is common.”
