One can never get bored with yoga. It is so versatile, so complete. It deals with how to help your body, how to help your mind find happiness and transform itself, to know and understand what “is” and so to know what should be called the Self. The whole philosophy and practice of yoga is developed for the good of each and every individual–so that he or she can find the Self individually, and thereby divine the undercurrent of happiness in all life.
~ Srivatsa Ramaswami in The Complete Book of Vinyasa Yoga
