In order to know what the Supramental Realisation will be like, the first step, the first condition is to know what the supramental consciousness is. All those who have been, in one way or another, in contact with it have had some glimpse of the realisation to be. But those who have not, can yet aspire for that realisation, just as they can aspire to get the supramental knowledge. True knowledge means awareness by identity: once you get in touch with the supramental world, you can say something about its descent, but not before. What you can say before is that there will be a new creation upon earth; this you say through faith, since the exact character of it escapes you. And if you are called upon to define realisation, you may declare that, individually speaking, it means the transformation of your ordinary human consciousness into the divine and supramental.
