"Nowhere else in the world at this present moment is there such a centre of influence—a centre constantly visited by the Great Ones, and therefore bathed in their wonderful magnetism. The vibrations here are marvellously stimulating, and all of us who live here are therefore under a constant strain of a very peculiar kind, a strain which brings out whatever is in us... To live at Adyar is the most glorious of all opportunities for those who are able to take advantage of it, but its effect on those who are constitutionally unable to harmonize with its vibrations may be dangerous rather than helpful. If a student can bear it he may advance rapidly; if he cannot bear it he is better away. (Introduction)"
