This supposes that there is a you, there is a me, and there is someone...Buddhists do not have a concept of "blasphemy."
Incorrect understandings of karma in the early sutras
In Buddhism, karma is not pre-determinism, fatalism or accidentalism, as all these ideas lead to inaction and destroy motivation and human effort. These ideas undermine the important concept that a human being can change for the better no matter what his or her past was, and they are designated as "wrong views" in Buddhism. The Buddha identified three:
Pubbekatahetuvada: The belief that all happiness and suffering, including all future happiness and suffering, arise from previous karma, and human beings can exercise no volition to affect future results (Past-action determinism).
Issaranimmanahetuvada: The belief that all happiness and suffering are caused by the directives of a Supreme Being (Theistic determinism).
Ahetu-appaccaya-vaada: The belief that all happiness and suffering are random, having no cause (Indeterminism or Accidentalism).[26]
Karma is continually ripening, but it is also continually being generated by present actions, therefore it is possible to exercise free will to shape future karma. P.A. Payutto writes, "the Buddha asserts effort and motivation as the crucial factors in deciding the ethical value of these various teachings on kamma."[27]
