There are, in the history of the earth, moments of transition when things that have existed for thousands of years must give way to those that are about to manifest. A special concentration of the world consciousness, one might almost say, an intensification of its effort, occurs at such times, varying according to the kind of progress to be made, the quality of the transformation to be realised. We are at precisely such a turning-point in the world's history. Just as Nature has already created upon earth a mental being, man, so too there is now a concentrated activity in this mentality to bring forth a supramental consciousness and individuality...

...Consequently, we are not here to repeat what others have done, but to prepare ourselves for the blossoming of a new consciousness and a new life. That is why I address myself to you, the students, that is, to all who wish to learn, to learn always more and always better, so that one day you may be capable of opening yourselves to the new force and of giving it the possibility of manifesting on the physical plane. For that is our programme and we must not forget it. To understand the true reason why you are here, you must remember that we want to become instruments that are as perfect as possible, instruments that express the divine will in the world. And if the instruments are to be perfect, they must be cultivated, educated, trained. They must not be left like fallow land or a formless piece of stone. A diamond reveals all its beauty only when it is artistically cut. It is the same for you. If you want your physical being to be a perfect instrument for the manifestation of the supramental consciousness, you must cultivate it, sharpen it, refine it, give it what it lacks, perfect what it already possesses.
