In the RC Church history, there are over 200 levitators. I've read as many biographies as I could get my hands on. In all cases, the prerequisite ingredient is out of body travel, what the Saints call "Going into Ecstasy.". Thus, there is 1. Frogic travel, 2. Yogic travel, and 3. Out of body travel. Typically, the Saint having gone into Ecstasy (while at prayer alone in a room, or in Church at the altar)), is unaware that such an experience is taking place. An observer may see the Saint in a kneeling position or lying down. Some have reported that in the case of the 17-th century Saint Stanislaus Papczynski, his eyes rolling up and down, back and forth uncontrollably and apparently unconscious.
Second necessary ingredient in the case of the RC levitators is devotion to Jesus and or Mary. Levitators in the Kriya Yoga tradition have an unsually advanced mastery of Breath, leading to out of body travel or levitation. It's not surprising that the Dome "levitators" have only reached the Frogic stage. They have no mastery when it comes to out of body travel, are not devoted to Jesus and Mary, and have no mastery over Breath, as do the advanced Kriya Yoga practitioners.
