Therefore, when the prophets and seers of all ages have given to humanity a certain message and law, it was only the giving of a drop from the ocean which they received into their hearts. And this also is a great difficulty, for even this drop is not intelligible. Does every Christian understand the Bible? Does every Muslim know the Qur'an, or every Hindu the Vedanta? No, they may know the words of the verses, but not always the real meaning. Among the Muslims there are some who know the whole Qur'an by heart, but that does not fulfill the purpose. The whole of nature is a secret book, yet it is an open book to the seer. How can man translate it? how can man interpret it? It is like trying to bring the sea on to the land; one can bring it, but how much?
