This volume brings together for the first time two classic booklets: The Foundation Stone and The Life, Nature, and Cultivation of Anthroposophy. The former contains Rudolf Steiner\'s comments of the Foundation Stone Meditation made during the refounding of the Anthroposophical Society at the Christmas Conference of 1923-24. This key meditation -- of which several alternative translations are included -- holds a central place in the meditative life of many students of Rudolf Steiner\'s work. The second booklet contains a number of letters that Rudolf Steiner wrote to members of the Anthroposophical Society following the Christmas Conference. In them he gave valuable thoughts on the new character of the Society and guidelines for its conduct and relation to the world following its refounding.
