Thanks retro, i am familiar with them
I know that one can become sick just because of natural contact with bacteria but there are occasions where it says it is because of past kamma, its this latter im addressing
There is no supernatural force or invisible hand directing the movement of beings to their respective destinations. Through our own volition, we are continually creating the seeds of our future. In the example you gave, of someone getting sick by way of bacterial or viral infection, past kammas
(be it by volitional actions, choices, words we have spoken, unwholesome thoughts we have concocted) will direct us to a future situation where we maybe in proximity to bacteria, viruses or other environmental factors that cause one or more genetic predispositions to become expressed.
But direction implies that "something" knows where that bacteria is in order for you to be directed to it
What i am getting at is since kamma is mental, as in it doesnt create the physical world in any sense, how does the result of kamma include a natural event of bacteria infecting a body, what is the distinction between the natural account given and the kamma account of the same event without just saying its past kamma?
