An inner connection exists between man’s activity and his organs. He needs his organs both for the lowest and the highest impulses. He also needs them in art. When someone has once and for all absorbed everything from the world, he has no further use for his organs. Between birth and death man accustoms himself to perceive the world through his organs. After death what he is thus accustomed to must slowly be put aside.
If he still wishes to make use of his organs to perceive the world, then he finds himself in the condition which is called Kamaloka. It is a condition in which there is still desire to perceive through the organs, which however are no longer there. If after death a person could say that he had no further desire to use his organs, Kamaloka would no longer exist for him. In Devachan everything which man formerly perceived around him with his organs, is there perceived from within — without organs.
