Thus, from a Buddhist point of view, our present mental, moral intellectual and temperamental differences are, for the most part, due to our own actions and tendencies, both past and present.
Although Buddhism attributes this variation to Karma, as being the chief cause among a variety, it does not, however, assert that everything is due to Karma. The law of Karma, important as it is, is only one of the twenty-four conditions described in Buddhist Philosophy.
Refuting the erroneous view that "whatsoever fortune or misfortune experienced is all due to some previous action", the Buddha said:
"So, then, according to this view, owing to previous action men will become murderers, thieves, unchaste, liars, slanderers, covetous, malicious and perverts. Thus, for those who fall back on the former deeds as the essential reason, there is neither the desire to do, nor effort to do, nor necessity to do this deed, or abstain from this deed."
It was this important text, which states the belief that all physical circumstances and mental attitudes spring solely from past Karma that Buddha contradicted. If the present life is totally conditioned or wholly controlled by our past actions, then certainly Karma is tantamount to fatalism or determinism or predestination. If this were true, free will would be an absurdity. Life would be purely mechanistic, not much different from a machine. Being created by an Almighty God who controls our destinies and predetermines our future, or being produced by an irresistible Karma that completely determines our fate and controls our life’s course, independent of any free action on our part, is essentially the same. The only difference lies in the two words God and Karma. One could easily be substituted for the other, because the ultimate operation of both forces would be identical.
