The kind of true interaction between souls should be established on earth which allows souls to develop the forces of freedom, which allows all human events great and small and all attempts to give form to human activity and creation to have as their aim that the human being holds the balance in his soul with regard to what lives and works spiritually. This must come to be an ideal.
The human being becomes free when he is in a position to acquire those soul forces in the external physical world as, for example, the can acquire them when he is able to follow the beautiful forms that live in an art that has its true source in spirit.
The human being becomes free when there is interchange and communion between two souls of such a nature that the one soul is able to follow the other with ever-growing understanding and with ever-growing love. If it is the human physical body with which we are concerned, then fraternity comes into play; if it is a question of the soul, then we have to look for the forging of those delicate and subtle links that arise between soul and soul, that must find their way right into the structure of our life on earth and must always work towards engendering interest, deep interest, in one soul for the other.
For in this way alone shall souls become free – and it is only souls that can become free.
Rudolf Steiner, The Knights Templar
