Enforcement Of Actionism.

The creatures experience the grief and happiness merely through the minute characteristics of the great five Elements. If one hears sacred words (Sacred Scriptures), touches the favourable persons and things, experiences favourable visions, tastes and smells, then he gets happiness, but if one does the reverse, then the creature gets Grief as outcomes (fruits) of his actions. Manu Smiriti. 1/29

The various creatures of different names, groups and casts, started to take births and rebirths (repeatedly i.e. again and again) and started to act accordingly (i.e. according to their names, groups and casts of birth) as enforced by the commands given to them by The Creator Brahma, at the very beginning of creation. Manu Smiriti. 1/30
As the next season comes with it's own characteristics automatically after passing of the present season, similarly the actions performances (the right and wrong actions as a whole) of the creatures come automatically to them, and according to their action performances, the creatures get birth in various different names, casts and groups of the creatures (for example lion, tiger, cow, deer, thief, pirate, brahmin, yogi, King, preacher and minister etc. Manu Smiriti. 1/31

As the change of seasons show up their symptoms automatically, similarly in the same manner, the creatures holding (occupying) their body receive their actions and behavior spontaneously and get their actions that are applicable to their body (self) automatically. Manu Smiriti. 1/32
