Che six lectures were given at the headquarters of Adyar, with the intention of simply sketching the fundamental ideas of Wisdom to an intellectual public as yet uneducated in these conceptions. Now here are these lectures published with the hope that they will reach a like public all over the globe and that they will be of some help in sowing the truths which will ensure the rapid progress of the human mind. Only Theosophy is able to stop this race towards the abyss towards which the West is rushing and, already, Theosophy seems to have achieved some success in its beneficial mission. It leads the young Aryan nations to the source of the ancient Aryan Wisdom. This little book simply marks the path that leads to Wisdom; everyone must climb this path, no one can replace any of us for this ascent.
