- Anti-rebirthist = ucchedadiṭṭhi = one extreme = suicide.
- Rebirth-lover = sassatadiṭṭhi = another extreme.
- Profit-follower = eightfold path = middle way.
1st and 2nd see brahmajālasutta.
3rd see dhammacakkappavaḍḍhanasutta. (I am in plan to re-translate this sutta, but I can't not done it now. So if something wrong, I am sorry. I can't not check it deeply now, because my english still not good enough.)
"There are these two extremes that are not to be indulged in by one
who has gone forth. Which two? That which is devoted to sensual
pleasure with reference to sensual objects: base, vulgar, common,
ignoble, unprofitable; and that which is devoted to self-affliction:
painful, ignoble, unprofitable. Avoiding both of these extremes, the
middle way realized by the Tathagata — producing vision, producing
knowledge — leads to calm, to direct knowledge, to self-awakening, to
Unbinding.
"And what is the middle way realized by the Tathagata that — producing
vision, producing knowledge — leads to calm, to direct knowledge, to
self-awakening, to Unbinding? Precisely this Noble Eightfold Path:
right view, right contemplate, right speech, right action, right
livelihood, right effort, right mindfulness, right concentration. This
is the middle way realized by the Tathagata that — producing vision,
producing knowledge — leads to calm, to direct knowledge, to
self-awakening, to Unbinding.
What is profit?
6 profit: self profit, the others' profit, public's profit (common interest), this life's profit, next life's profit, and nibbāna-profit. (pali for search: attattha, parattha, attaparattha, ditthadhammika, samparāyika, and paramattha.)
Self profit, the others' profit, and public's profit (common interest) are done together by sati.
"Because of what I have said here, monks, you should train yourselves
such that the gifts of those whose requisites we use — the robes,
alms-bowl, chair, bed, and medicine as a support when sick — will have
great fruits, great merits [for the people who give them], and our
going forth will not be in vain, will be fruitful, will have a result.
Thus should you train yourselves, thoroughly seeing that for your own
benefit, monks, it is right to strive with heedfulness; thoroughly
seeing that for the benefit of others, monks, it is right to strive
with heedfulness; and thoroughly seeing that for the benefit of both,
monks, it is right to strive with heedfulness."
This life's profit and next life's profit are done together by sati (appamāda). So, person who do just this life's profit or next life profit is pamāda person. see:
http://www.accesstoinsight.org/tipitaka/sn/sn03/sn03.017.than.html
Nibbāna profit can be accessed by practitioner after he perfect finished to meditate magga. And that magga can start to meditate after sīla is done.
SN 45.149 Just as, bhikkhus, whatever actions are to be performed with
strength are all performed on dependence on the earth, supported by
the earth; in the same way, bhikkhus, it is on dependence on virtue,
supported by virtue, that a bhikkhu develops the noble eightfold path (magga),
that he cultivates the noble eightfold path.
Above sīla give this life's profit and next life. See (1st-4th are this life's profit, 5th is next life's profit):
Mahāparinibbānasutta
24. "Five blessings, householders, accrue to the righteous man through
his practice of virtue: great increase of wealth through his
diligence; a favorable reputation; a confident deportment, without
timidity, in every society, be it that of nobles, brahmans,
householders, or ascetics; a serene death; and, at the breaking up of
the body after death, rebirth in a happy state, in a heavenly world."
So, anti-rebirthist & rebirth-lover are pamādo (person who has not meditating mindfulness).
That is one of many reasons that why I, who have never seen any ghost or any spirit, am not deny next life.
