There are many people, particularly in our materialistic age, who ask why they should concern themselves with life between death and rebirth or, if the idea of repeated earth lives is rejected, with an existence after death, since they surely can wait and see what happens after death when the time comes! This is said by people today who have not quite lost the feeling for the spiritual world but who are not yet equipped with sufficient soul-powers to acquire concepts and feelings about the super-sensible. They add that if they perform their duty here on earth, they shall experience in the appropriate way what awaits them after death.
Now a genuine connection with life between death and rebirth brings out clearly the fallacy of such a view and how important it is during earthly existence to have formed an idea of the conditions of life after death.
