The soul has a star on heaven.
If the soul praises the Lord, even after death its star, the angel, praises God on high in the voice of the rightenous man who used to do so, so that the Holy One will remember his spirit and his offspring.
This star is in heaven from the six days of creation, so that those who observe the commandments will be rewarded as if they had busied therselves with the study of the Law from the time that the world was created until the time of the resurrection of the dead.
