They were respected for these functions but they were also feared sorcerers able to work black magic. Their numbers too were large enough to put them in competition with one another. Individual success was attributed to the power of the deities with whom they identified, and who took possession of them in their frenzied dancing. The Tagalog word “olak” according to Ferdinand Blumentritt is a term for the trembling of the whole body of the catalona, when she becomes possessed by the devil (anito).

A person is believed to be composed of at least two souls—the breath of life (ginhawa or hininga, which stays with the living body) and the astral soul (the kalag or kaluluwa, which can travel to the spirit world). The ginhawa is believed to reside in the pit of the stomach (usually the liver), while the kalag resides in the head. The ginhawa represents the person's body and bodily urges; while the kalag represents the person's identity, mind, and strength of will. Both are required in a living person. Natural illnesses are the result of damage to the ginhawa. While they do not require a shaman, they are still important, as the death
