An “Oase” (the Dutch word for Oasis) is a place where you can find vegetation and life in an extremely dry area like for example a desert due to the presence of water. It’s a place for the wanderer to settle down for a while and take a rest in the shadow after a long journey. A place where piece an quiet can be found and everything is in balance. A place that provides the energy and vitality that we need to charge our battery to keep going and to stay alive.
Figuratively speaking an “Oase” is also a place where you can find peace of mind within yourself. A similar effect can be obtained, just by imagining this place in your head.
