The dominating condition (bdag-rkyen) that determines the type of cognition how one is aware of something. 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.
