The dominating condition (bdag-rkyen) that determines the type of cognition a way of being aware of something is. In the case of the five types of sensory cognition, it is the photosensitive cells of the eyes, the sound-sensitive cells of the ears, the smell-sensitive cells of the nose, the taste-sensitive cells of the tongue, and the physical-sensation-sensitive cells of the body. In the case of mental cognition, it is the immediately preceding moment of cognition.
