Knowledge of the Heart-Surya Vidya

Surya-Vidya, the Solar Knowledge—this was a name sometimes given to the Teaching of the Heart, a name that expressed the fieriness, the sun-like quality, and the centrality of the heart. In fact, anyone who wishes to get to know the heart cannot just approach it as a part of the organism. First of all the seeker should recognize the central nature of the heart and study outward from it, not inward toward it. The solar plexus will be the antechamber for the Temple of the Heart. The Kundalini will be a laboratory for the heart. The brain and all the nerve centers will be estates for the heart, because nothing can live without the heart! To a certain degree, even the brain can find substitutes. Even the Kundalini can be somewhat nourished by an electrical manifestation, and the solar plexus can be strengthened by blue light. But the heart stands as the Temple of humanity. One cannot conceive of the unification of humanity by means of the brain or the Kundalini, but the radiance of the heart can bring together the most seemingly diverse organisms, and even work over great distances in doing so. This experiment of bringing together hearts over long distances is waiting for workers to carry it out.
The wish to launch lengthy experiments is perfectly correct, because through them one can create another bond between the generations.
