A quotation on sun yoga from The Splendour of Tiphareth by Omraam Mikhael Aivanhov says: "Each of the other types of yoga helps to develop one particular aspect of oneself, whereas Surya-yoga activates all our psychic centres. When we unite our selves with the sun we are bound to get results, for we are uniting with the central power that governs and animates all the planets of our universe. This is why I say that all the other kinds of yoga, which were once considered so wonderful - and which are, indeed, still wonderful - will one day be replaced by Surya-yoga which surpasses them all, for when you work with the sun you are working with God Himself.
