(result of the belief there must be an opposite of something, good, bad,etc.)

in Buddhism (particularly Zen) this refers to the apparent separation of me from other than me.

When used as a religious term, this denotes the separation of two opposites and places those characteristics into two God forms. For example, good and evil, as characterized by the Christian God and Devil.

The sensation of realizing you are existing in two separate bodies, the physical body and its projected double, during an OBE. Duality is caused by the mind-split effect, and is usually only realized when perceptions are received from both bodies simultaneously. I.E., a projector is operating at a remote location from their physical body, but are still aware of some sensory input, usually sounds and tactile senses, coming from their physical body. The center of consciousness will also often flicker back and forth, between the physical and its projected double during an OBE. Also see: Mind-Split, Mind-Split Effects, Remote Eye.

The separation of human thought, emotion, and creation from Oneness with God. Duality creates the illusion of fear in opposition to the Truth of Divine Love.

Duality is the belief in two separate and opposing powers. We believe that God is all powerful and everywhere present, thus there can be no other power.

The mistaken perception separating the perceiver and the world, self and other, this and that.
