It often puzzles the student of elementary theosophy to be told that the soul passes through the purgation of the astral plane and goes on into the heaven world only to return to another incarnation and later to again enter the astral purgatory. Why, it is asked, must one who has thus been purified be again purified? The astral reactions are the results of the blunders made in each incarnation. Each of us in any given incarnation creates by his wrong doing the purgatory that awaits him after death. If he does no wrong there cannot possibly be any reaction. As a matter of occult fact the average good man will find the astral plane life a happy existence and will soon pass on to the blissful heaven world. As for the evil doer the suffering relates only to his evil deeds. Let us say he has committed murder. When the reaction of the evil force he has generated is over and he passes on into the heaven plane it does not mean that he is incapable of future evil. It means that he has probably learned thoroughly the lesson that it is very foolish to take life. But there are many other lessons he has not learned. When he passes into the heaven world he leaves all evil behind him. He is as one who puts his shoes aside to enter a temple. The astral body, like the physical, has perished and it is the freed soul that enters the heaven world. But when he returns through the astral plane to reincarnation he is clothed again in astral matter and this new astral body is exactly representative of his attainments in evolution. In his coming incarnation he will have other physical plane experiences and learn other lessons. The next time probably he will not kill, but perhaps he will cheat and steal or be a drunkard. These errors will react upon him in the astral life that follows. In a coming incarnation he will be wise enough to be temperate and neither cheat nor steal; but perhaps he will be a gossip and work much evil through slander. This in turn will bring its pain. And so in time he will learn to generate no evil force at all but to live in good will and helpfulness toward everybody. Then his progress will be rapid indeed, his life on all planes will be happy and the painful part of human evolution will be over.
