As the Buddha taught:
"Do not think a small sin will not return in your future lives.
Just as falling drops of water will fill a large container,
The little sins that steadfast accumulate will completely overwhelm you.
Do not think a small virtue will not return in your future lives.
Just as falling drops of water will fill a large container,
The little virtues that steadfast accumulate will completely overwhelm you."
I'm a FIRM beleiver that if you do good, good things will happen to you. The same goes for spreading lies and being malicious.
