Even though I am Catholic, I am discovering the Truth of the existence of karma through personal experience in my own spiritual journey.

There is a certain habitual sin that I am struggling with. After reading the Buddha's teaching, he said that when habitual sin repeats, it is because there is a pattern of karma that comes together under very specific logical conditions (conditions that can be numbered 1, 2, 3) to result in you making the choice to sin.

What strategies does the Buddha offer to:

1. Loosen this bad karma
2. Discover the logical conditions that cause this sin to repeat
3. Change the context so that the logical conditions causing this sin no longer arise?
