The term "ole" (usually sung at soccer games and bullfights) was originated centuries ago in Northern Africa during tribal dance gatherings. Once in a while a dancer would move in such an incredible way that the spectators would chant "Allah Allah". They believed that in that moment, God entered the dancer's body, giving them the power to go beyond human capabilities. When the Moors invaded Spain they took this custom with them but the pronunciation changed from Allah to ole.
When striving for greatness, we sometimes tap into a hidden energy and gain the ability to rise above ourselves. Whether you believe it's caused by God or by an inner strength, it's a state of being that we need to cultivate.
