In no order of importance:
1) 琉璃王子: He defied the Buddha's intervention to prevent the
massacre of the Sakya clan. I think he will go to hell. If he has
gone to hell, I wonder how he is now. I worry for him.
2) Sariputra: He gouged both his eyes to help a person who
wanted a practitioner's eyes for brewing medicine for his blind
mother. However, because his eyes were crushed by the
person as it was regarded as filthy, Sariptura regressed
on the spot and regretted making the vow to become a Bodhisattva.
From then on he cultivated as smaller vehicle practitioner for
many lifetimes.
But in Lotus Sutra, Sariptura (舍利佛) was given the future Buddha
to be prediction by the Buddha. You don't know how happy I was to
read about that! ^^
3) 阿阇世王子：He ordered for the starvation of his father and almost
tried to kill his mother. However, he was later saved by the
Buddha and was predicted by the Buddha that he would become a
Buddha in the future.
4) 提达婆多 (Devadatta): He had tried to kill the Buddha many times
but only came close to doing it on one occasion. That particular
incident caused the Buddha's feet to bleed and that was considered
as hurting the Buddha, a very grievous karma that sentenced him to
many aeons in hell.
However, in the Lotus sutra, the Buddha clearly states that
Devadatta, after his suffering is over, would attain Buddhahood and
would be known as 天王佛.
Yeh! Yippee! Worry number 3 solved. ^^
5) 善星比丘：This monk went around refuting Buddha's teachings,
directly or indirectly implying that Buddha's teachings are false
or wrong. He would also try to sweep the footprints of the Buddha
on the roads so that people would not be able to find the
Buddha.
I read about him in 《佛说大涅磐经》, from which I learned the term
'icchantika' or 一阐提. I was so sad cos I knew this monk's deeds is
equivalent to slandering the Triple Gems and the negative karma is
so heavy that the Buddha likened it to trying to pull a person out
of a cesspit through a single strand of his hair. No matter how
hard one can try, the victim can never be saved.
The Buddha also mentioned that if one kills an icchantika,
there would be no negative karma for the aggressor, cos there is no
single strand of good karma in an icchantika. An icchantika is one
with no past or present good karma in him/her, according to the
Buddha.
The best glimpse of hope offered by the Buddha in the same sutra
was that Buddha nature is neither past, present nor future and has
no nature of being created or destroyed, hence in the future when
circumstances allow, the icchantika would still have a chance.
I was so depressed even after reading about this verse which
offered the slightest glimpse of hope, that I found it difficult to
sleep that night. But I'm less affected now. Although feelings of
sympathy and hopelessness are still around...
