7. Evil in the Light of Spiritual Knowledge
It follows from this, that a human must in fact protect him or herself from that which in one field, in one world is excellent, namely the lifting up of the inner soul into another world so as to somehow use it at the highest level to achieve the spiritual world; but that must be stricken by evil and by the worst, if a human permits him or herself be penetrated by what he/she must live out of as his/her being in the physical-sense world: what is useful to him/her as worthy preparation for the kingdom of the spirit. Thus we must precisely be strong in the spirit between death and new birth, in the strengthening and empowering of our I, with which we can prepare for ourselves such a physical sense being, so that in outer existence, in the acts and thoughts of the physical world we can be as unselfish as possible. We must use our selfishness before our birth in the spiritual world to work upon ourselves; we must look upon ourselves in such a way that we can become unselfish in the physical world, that is to say, moral.
