It is like a person who says to his friend, “Work with me for just a minute, and in return I will give you every pleasure and treasure in the world for the rest of your life.” There is indeed no greater free gift than that, since the reward is utterly incomparable with the work, since the work is in this world, a transient, worthless world compared to the reward and the pleasure in the eternal world.
Question: So is there reward after death or not?
Answer: After which death? If the animate body dies, it gets buried. But if the egoistic desire dies, then that’s not the end. After that it is necessary to “revive the dead”—the dead desire.
First it is necessary to “bury” the egoistic desire, to read the commemorating prayer over it (Kaddish), to bless the Creator for the fact that my egoism has died. I say, “You have killed my egoistic desire and I am very grateful to You for that! Now let’s continue working. Let’s revive the dead and give it the intention for the sake of bestowal!”
