Yoga is primarily the method and result of meditation. Philosophy accepts and uses this method and incorporates its results. But it does not stop there. It adds two further practices, metaphysical reasoning and wise action, and one further effort--the mystical insight into, and distinction of, the ego. Therefore we are justified in saying that the hidden teaching does go beyond yoga.
