One may say, 'I seek for knowledge', but there are two kinds of knowledge. The one kind of knowledge is that of names and forms, in other words, the knowledge of facts. But there is a difference between a fact and truth. In our everyday language we often confuse these two words, and we say truth for fact and fact for truth. In order to attain to higher knowledge we should not try to gain it in the same way as we try to gain outer knowledge of names and forms. The outer knowledge we gain by learning; the inner knowledge we gain by unlearning. The inner knowledge we can only gain when the heart is tuned to its proper pitch.
