Sri Aurobindo
Letters of Sri Aurobindo
Volume 1
I find there is no chance of finishing any long letter on the Supramental today – for the Overmind has heaped Andes on Himalayas and the Alps on the Andes (paper of course) and buried me underneath the mass. So I shall only pen a few passing answers to details today.
First, what is a perfect technique of Yoga or rather of a world-changing or Nature-changing Yoga? Not one that 
takes one man by a little bit of him somewhere, attaches a hook and pulls him up by a pulley into Nirvana or Paradise? The technique of a world-changing Yoga has to be as multiform, sinuous, patient, all-including as the world itself – has it not? If it does not deal with all the difficulties or possibilities and carefully deal with each necessary element, has it any chance of success? And can a perfect technique which everybody can understand do that? It is not like writing a small poem in a fixed metre with a limited number of modulations. If you take the poem simile, it is the Mahabharata of a Mahabharata that has to be done. And what, compared with the limited Greek perfection, is the technique of the Mahabharata?
Next, what is the use of vicārabuddhi in such a case? If one has to get a new consciousness which surpasses the reasoning intellect, can one do it on lines which are to be judged and understood by the reasoning intellect, controlled at every step by it, told by the intellect what it is to do, what is the measure of its achievements, what its steps must be and what their value? If one does that, will one ever get out of the range of the reasoning intelligence into what is beyond it? And if one does, how shall others judge what one is doing by the intellectual measure? How can one judge what is beyond the ordinary consciousness when one is oneself in the ordinary consciousness? Is it not only by exceeding yourself that you can feel, experience, judge what exceeds you? What is the value of a judgment without the feeling and experience?
What the Supramental will do the mind cannot foresee or lay down. The mind is Ignorance seeking for the Truth, the supramental by its very definition is Truth-Consciousness, Truth in possession of itself and fulfilling itself by its own power. In a supramental world imperfection and disharmony are bound to disappear. But what we propose just now is not to make the earth a supramental world but to bring down the supramental as a power and established consciousness in the midst of the rest – to let it work there and fulfil itself as Mind descended into Life and Matter and has worked as a Power there to fulfil itself in the midst of the rest. This will be enough to change the world and to change Nature by breaking down her present limits. But what, how, by what degrees it will do it, is a thing that ought not to be said now – when the Light is there, the Light will itself do its work – when the Supramental Will stands on earth, that Will will decide. It will establish a perfection, a harmony, a Truth-creation – for the rest, well, it will be the rest – that is all.
This is only a preface – the book follows.
