05. Sadhana through Work
As you have opened yourself to the Force and made yourself a channel for the energy of work, it is quite natural that when you want to do this work the Force should flow and act in the way that is wanted or the way that is needed and for the effect that is needed. When one has made oneself a channel, the Force is not necessarily bound by the limitations or disabilities of the instrument; it can disregard them and act in its own power. In doing so it may use the human instrument simply as a medium and leave him as soon as the work is finished just what he was before, incapable in his ordinary moments of doing such good work; but also it may by its action set the instrument right, accustom it to the necessary intuitive knowledge and movement so that it can at will command the action of the Force. As for the technique, 
there are two different things, the intellectual knowledge which one applies and the intuitive cognition which acts in its own right, even if it is not actually possessed by the worker. Many poets, for instance, have little knowledge of metrical or linguistic technique and cannot explain how they write or what are the qualities and elements of their success, but they write, all the same, things that are perfect in rhythm and language. Intellectual knowledge of technique helps of course, provided one does not make of it a mere device or a rigid fetter. There are some arts that cannot be done well without technical knowledge, e.g. painting, sculpture.
What you write is your own in the sense that you have been the instrument of its manifestation – that is so with every artist or worker, though of course for sadhana it is necessary to recognise that the real Power was not yourself and you were simply the instrument on which it played its tune.
The Ananda of creation is not the pleasure of the ego in having personally done well and being somebody, that is something extraneous which attaches itself to the joy of work and creation. The Ananda comes from the inrush of a greater Power, the thrill of being possessed and used by it, the āveśa, the exultation of the uplifting of the consciousness, the illumination and its greatened and heightened action and also the joy of beauty, power or perfection that is being created. How far one feels it depends on the condition of the consciousness at the time, the temperament, the activity of the vital; the yogi, of course, (or even certain strong and calm minds) is not carried away by the Ananda, he holds and watches it and there is no mere excitement mixed with the flow of it through the mind, vital or body. Naturally the Ananda of samarpaṇa or spiritual realisation or divine love is something far greater, but the Ananda of creation has its place.
