An example from National Geographic
: The fire ant has a new predator. A rare species of fly kills fire ants by impregnating its brain with its children. The maggots then take control of the ant's behavior while feeding on its brains, eventually hatching into flies (during which, its host obviously dies).
Now, two questions:
#1. From a classic Theravadin point-of-view, would these two creatures be regarded as sentient beings?
#2. If yes, then what is being controlled or manipulated by the fly? The ant's entire set of Five Aggregates or merely some of them?
The above is merely just an example, though... What I'm getting at is the broader question: In what ways can one being influence another's aggregates or kamma?
