One should not believe that when one glimpses behind the veil of the senses and reaches the region beyond the threshold, that one ends up in a realm of pure beauty. Do not think that someone who cognisant of these worlds expresses himself light-heartedly when he says: if people are not carefully prepared, they need to be held back when coming to the threshold of the spirit world. – Because it is essential that one first of all gets to know the totally unedifying foundations, before one experience what in a sense is elevating and wholesome behind the curtain.
