There is another consideration. Whatever is continuous disappears from our perception, whereas anything that is momentarily tangible becomes visible to us. This is shown when we start on a sea voyage. At first the noise of the engines is almost unbearable, but as we go on we get accustomed to it, so that after four or five days we find that we do not notice the noise any more, while at the same time we can hear the least whisper of a friend speaking to us. The continuous noise is now no longer audible unless we stop, to pay attention to it.

It is just like this with the whole mechanism of the universe. It is audible all the time; it is visible both externally and inwardly - but we are so concerned with our own activities, with the things we ourselves are interested in, that our consciousness can only retain these and pays no attention to all the other things, loud as they are.

There are two things to consider: (1) the mastery of the mystery itself, and (2) the insight into the mystery, its perception. To gain insight into things the mystic enters into the depths of the whole mechanism of the universe by educating his senses to be keen enough to see and hear the working through it all, throughout the whole cosmic system. Taking these two senses as his means of investigation he dives deep into the universal life.
