10. Spirits cannot aspire to complete happiness till they have become pure. Any kind of stain prohibits entrance into the blissful worlds. It is like the passengers on a plagued ship who find themselves prohibited from entering port until they have undergone a cleansing. The imperfections of Spirits are slowly overcome by means of various corporeal lives. The tribulations of life, when well supported, help them towards progress. They erase faults and find purification by means of atonement, which is the remedy which cleanses the sores and heals the sick. The more grave the illness, the more energetic must be the remedy. Therefore, those who suffer greatly must realise that they have most to atone for, and should rejoice in the proximity of the cure. It will depend on each one to take every advantage from suffering, by being resigned and not spoiling things with impatience, seeing that, if that be the case, they will then have to begin all over again.
