"Life work" means that to which one will devote one's energies. It is the world of the soul, as well as the material work done in the visible world. These categories of tasks are not separate: they are not inimical to one another any more than sweeping the temple, washing the vestments, or cleaning and arranging the altar are inimical to the act of prayer. On the contrary, these tasks are prayer. They are the work of the soul in that they provide a suitable atmosphere for the cultivation of a contemplative and receptive attitude.
Every person has a share in this world and a share in the world to come. We understand the concept of a share in the world to come, but what does it mean having a share in this world? Open your hearts. Having a share in this world means I know exactly what I have to do in this world. This is a very high level. If I know that if I don't do it, it just won't happen. Then I've just got to do it. This is my share in this world.
