Thus by the good-will, intelligence, unselfishness, and love of the remaining friends the passing Spirit is enabled to enter the new conditions under much more favorable circumstances, and students of the Higher Philosophy cannot do better than to spread this teaching as widely as possible. For those who have evolved spiritual sight there is of course no death, but even those who have studied the Higher Teachings may in a measure be said to have attained this great victory. That all depends. The usual time between two births is a thousand years, so as to give people a chance of being embodied once as a man and once as a woman while the Sun is passing through each sign of the zodiac by precession, which takes about 2,100 years. This is done because the lessons during that period are so many and so different that they cannot be effectively learned in the same sexual type of body.
Experiences are very different from the standpoint of a man and that of a woman.
But this law is like all other laws of nature, it is not blind. It is under the dominion of four great Beings called the Recording Angels, and they have to do with all the details of human evolution. They see that everyone gets a chance to obtain as much experience as he or she can stand. If it is necessary for a person to remain the whole one thousand years in the invisible worlds, he remains. If not, he comes back sooner.
