I was reading through the Jataka stories about the Bodhisatta's pat lives who lived to perfect his paramis, and there upon came a question to my mind when I finished reading about Vessantara Jataka, and the story where he threw himself to the hungry tigress to avoid her from eating her own cubs. I may have interpreted it wrongly, but to me, his acts of life-sacrifice seem to be similar with suicide. And according to my understanding, those who commit suicide are actually taking away their own lives (breaking the 1st precept) and would have heavy, bad karmic consequences. Would those life-sacrifices that the Bodhisatta commit fall under this category? Why or why not?
