The question may be asked whether inner concentration and the other means described for the attainment of supersensible cognition permit us to observe only in a general way what happens between death and a new birth or other spiritual events; or whether they furnish the possibility of observing quite definite events and beings, as, for example, any given deceased person. To this we must answer that one who has acquired the ability to see in the spiritual world by the methods explained, can also perceive particular events which occur there; he acquires the power of putting himself in communication with individuals living in the spiritual world between death and a new birth. It must be observed, however, that in an occult sense this ought to take place only after the proper training required for supersensible cognition has been undergone. For not until then is it possible to distinguish between illusion and reality, in regard to certain events and beings. A man who tries to observe particular cases without due instruction, may fall a victim to innumerable deceptions. The training which leads to the observation in higher worlds of what has been described in this book, also leads to the ability to trace the post-mortem life of any special individual, and no less does it lead to the observation and comprehension of all psycho-spiritual beings who, from the hidden worlds, work upon the visible ones. Correct observation of individual cases is only possible, however, on the basis of a knowledge of the universal great facts of the spiritual world,—facts regarding the world and humanity which concern every human being. The desire for the one without the other, leads one into error. FOOTNOTES 1 We may also say, it could only live the life of a plant in the physical body.
