Here on earth we human beings are citizens of two worlds. As physical beings we are a part of this material world. But our soul – that is, our actual personality – is spiritual in nature. It has stepped into this earthly existence from the world beyond in order to acquire merits and become spiritually stronger. On earth, however, incarnated in a physical body, human beings so easily forget where they have come from and the kind of task they entered this earthly existence with; the world is too noisy, the distractions too great for us to hear the quiet voice of heaven. How can we as human beings nevertheless succeed in maintaining the bond with our spiritual home and in giving our soul the attention and nourishment it needs? These questions and more are dealt with in this themed issue.
