Aliya is the Jewish immigration to Israel. It comes from the verb lealot - to raise. You need to move when you feel that you don't belong to your current place. You have to raise above the deep roots that you have, because you are drying out(the trees). You have to overcome the burdens of the journey (the desert behind the trees). Your previous experience and background will help you to establish in the new place (the small town near the mountains). The life there would not be easy, those are pretty dangerous mountains surrounding this small place.But when a man has an ideal, a dream, he can move everything, even mountains.
