We are in an age, full of the throes of travail, when all forms of thought and activity that have in themselves any strong power of utility or any secret virtue of persistence are being subjected to a supreme test and given their opportunity of rebirth. The world today presents the aspect of a huge cauldron of Medea in which all things are being cast, shredded into pieces, experimented on, combined and recombined either to perish and provide the scattered material of new forms or to emerge rejuvenated and changed for a fresh term of existence. Indian Yoga, in its essence a special action or formulation of certain great powers of Nature, itself specialised, divided and variously formulated, is potentially one of these dynamic elements of the future life of humanity. The child of immemorial ages, preserved by its vitality and truth into our modern times, it is now emerging from the secret schools and ascetic retreats in which it had taken refuge and is seeking its place in the future sum of living human powers and utilities. But it has first to rediscover itself, bring to the surface the profoundest reason of its being in that general truth and that unceasing aim of Nature which it represents, and find by virtue of this new self-knowledge and self-appreciation its own recovered and larger synthesis. Reorganising itself, it will enter more easily and powerfully into the reorganised life of the race which its processes claim to lead within into the most secret penetralia and upward to the highest altitudes of existence and personality.
