Rupa
Since the material body called kalala (clear fluid) accompany the arising of the first birth-consciousness (patisandhi citta) we should understand the course of arising and ceasing of the material body throughout one's life. Hence we propose to deal with what should be known of rupa (Matter) in this chapter.
Rupa literally means that which changes its nature. The causes of change are many; they include heat and cold. In very cold climate your skin cracks, and the pigment changes; you catch cold and fall ill. In the group of purgatories called Lokantarika, the sinners drop into very cold water and are crushed to death. In hot climate your skin get inflamed and redden; you get burns and scalds; you get sunstroke. Moreover you may be bitten by mosquitoes, pests, dogs or snake; some of these bites may be fatal. Hunger and thirst may also kill you. These are examples of the changing nature of rupa.
