Mind is not always so unruly; it proves to be unruly when it wants to rule itself. It is like the body: one may feel restful sitting naturally, but as soon as one keeps quite still for five minutes, the body begins to feel restless; and it is still more difficult to make the mind obey. Mystics therefore find a rope to tie the mind in a certain place where it cannot move. What is that rope? That rope is breath. It is by that rope that they bind the mind and make it stand where they wish it to stand. It is like the bird which uses its saliva to make its nest; so is it with the mystic who out of breath creates atmosphere, creates light and magnetism in which to live.
