"When in the far future the time shall come for the advent of another Buddha, and the present Bodhisattva takes that final incarnation in which the great step will be achieved, He will preach the Divine Law to the world in whatever form may seem to Him most suited to the requirements of the era, and then will follow Him in His high office the Master Kuthumi, who has transferred Himself to the Second Ray to take the responsibility of becoming the Bodhisattva of the sixth root race."
