You're nourishment

When you go, you will be nourishment to the land and the ppl there. You're like the grass, the water and the gardener. You will bring new grass to the land.. and where there's one grass, it spreads very fast. You water it and it will grow bringing new life to the land.

I see a fountain of water and fresh grass growing and reproducing and soon the land is a whole green garden.

So your role/you will be this nourishment. Bringing in new life a fresh new living water.
