Desire is the force behind all things; it is the moving principle of the universe and the innermost centre of all Life. Hence, to take the negation of desire for our primal principle is to endeavour to stamp out Life itself; but what we have to do is to acquire the requisite knowledge by which to guide our desires to their true objects of satisfaction. To do this is the whole end of knowledge; and any knowledge applied otherwise is only a partial knowledge, which, having failed in its purpose, is nothing but ignorance. Desire is thus the sum-total of the livingness of Life, for it is that in which all movement originates, whether on the physical level or the spiritual. In a word, desire is the creative power, and must be carefully guarded, trained, and directed accordingly; but thus to seek to develop it to the highest perfection is the very opposite of trying to kill it outright.
