In the Malagasy culture, the *tody* is linked to the *tsiny*. *Tsiny* can be translated as reproach or blame. If one person receives too much *tsiny*, it is believed something bad will happen to him/her. So, *tody* is some kind of bad karma retaliation. It cannot be triggered, it's just brought by fate. Still, it's different from karma because if you do something bad but nobody notice it, you won't receive *tsiny*. Also, the *tody* won't necessarily retaliate on the faulty person. It may bring bad omen to one descendant.
