Then suddenly holiness comes into the world. Everything is growing. Everything is bearing fruit. Someday, Someday, G-d will revive the dead. Pesach is the time of the beginning of summer.
Every year there is a little revival of the dead.
All of us are half dead. Whenever we give up, we are dead, we are on the level of winter. When we don't give up we are on the level of summer. If a person is really deep enough, every summer he can taste a little bit of the great reviving of the dead which will take place sometime, someday. G-d will show us that there is no such thing as death.
