Rudolf Steiner suggested certain essential exercises to protect against dangers that can accompany meditation itself. These "accompanying" exercises protect by helping us develop inner certainty and strength- achieved, for example, by intensifying thinking, controlling the will, and mastering our emotions. Such exercises are described in detail, with advice on how to practice them. The author also tells us that they help develop and strengthen living thinking, and consequently a whole new means of perception-the heart chakra. Here is encouragement and stimulus for any path of spiritual development.
