When we see, hear, smell, taste, experience an object through the body- sense or through the mind-door, there is not only one citta experiencing the object through the appropriate doorway, but a series or process of cittas. A rupa which impinges on one of the senses is experienced by a series of cittas. When that sense-door process is over, the object is experienced by cittas through the mind-door. Sense-door processes and mind-door processes arise and fall away continuously.

This series or process of cittas which arise through the sense door process or the mind door process are called javana cittas.
