If between birth and death no knowledge of the supersensible world is developed, this will mean blindness in the life in the supersensible world between death and a new birth, just as the absence of eyes means blindness in the spatial organism. Man passes through death even if on Earth he acquires no knowledge of the supersensible world; but he enters then into a world where he sees nothing, where he can only grope his way about.
This is the agonizing experience that is the natural corollary of the materialistic age for one who has true insight into Initiation-Science today. He sees how men on Earth lapse into materialism; but he also knows what this lapse means for the spiritual life. He knows that it means eradication of the eyes, that in the existence awaiting them after death, men will only be able to grope their way about. In olden times, when there was instinctive knowledge of the supersensible world, men passed through the gate of death able to see. That old, instinctive supersensible knowledge is now extinct.
Today, spiritual knowledge must be consciously acquired — spiritual knowledge, I say, not clairvoyance. As I have always emphasized, clairvoyance too can be attained, but that is not the essential here. The essential thing is that what is discovered through clairvoyant research shall be understood — as it can be understood — by ordinary human reason, healthy human reason. Clairvoyance is needed to investigate these things, but it is not needed for acquiring the faculty of sight in the supersensible world after death.
