This topic is probably more appropriate for western
materialists. I think Asians accept rebirth easier. But just
sharing.

Nowadays Buddhist-inspired meditation and mindfulness seems to
be accepted by non-Buddhists, after stripping out the 'religious'
parts. It's good that it helps people in their lives. But it's like
there's also a trend for atheistic/secular Buddhism where people
follow the philosophy, but don't subscribe to the beliefs in karma
and rebirth and other 'religious' parts. Some people like to say
Buddhism is philosophy by the historical Buddha and it is people
who made it into a religion.
What's your take on it?
This is a good question.
Those who strip out rebirth and karma are stripping out the basis
for practicing for liberation. That is, they only experience the
meagre benefits of calm abiding in their meditation, but they will
never experience the benefits that the wisdom of dharma has to
offer which leads towards the liberation from afflictions (passion,
aggression and delusion) - the causes of samsara and rebirth. All
they want will be some inner peace, but they will never get to the
true import and goal of Buddhadharma which is Nirvana.
Since all they have is one life (a.k.a. 'YOLO'), there is no need
to care about future life at all, other than to just enjoy one's
life in a hedonistic way. Meditation is merely just a means for
them to experience some relaxation.
When my spiritual mentor, lets just call him X because he likes
anonymity, recalled numberless past lives and faces in his
meditation samadhi one day long long time ago, he got sick of it
and realized the necessity to be liberated. He also got the sense
that this life is really not very important at all (other than to
practice, that is), what used to be very important turns out to be
quite meaningless.
Got another time long long time ago, King Yama (lord of the death,
a.k.a 阎罗王) and another spirit were speaking to each other when he
was meditating - and both of them were saying that he has not
overcome death. He did not even know who 'yama' was at that time,
but he heard a voice addressing Yama and Yama said oh, so that was
the one who has not yet overcome death. When he came out of
meditation he went to find out what 'yama' is. Why did yama appear
in his meditation? I do not know, maybe to serve as a reminder. He
was already quite experienced and had certain realization at that
time, but it is always good to remind ourselves that the path is
long ahead and not get carried away.
If we are real practitioners of Buddhadharma who accept rebirth and
karma, we must not kid ourselves, death is our real test. Until we
have perfected our practice and attained complete liberation, we
must never be satisfied with some results in practice, we must
never satisfied with our realization, much less what those atheist
get out of meditation (some minor relaxation or peace, which is
meagre). On the other hand if there is no rebirth, then everyone
will achieve 'Nirvana' at death without practice so one can just
relax and take things easy and just enjoy life as it is, therefore
such a view is fundamentally at odds with the Buddhadharma and is
totally not appropriate for real practitioners. Thinking about
death and rebirth everyday will instill a sense of urgency and
necessity for practice which will never come if we reject
rebirth.
X also said in 2006:
"Life is like a passing cloud, when it comes to an end, a hundred
years is like yesterday, like a snap of a finger. If it is only
about one life, it really doesnt matter whether we are enlightened.
The insight that the Blessed One has is not just about one life;
countless lives we suffered, life after life, unending. Such is
suffering.
It is not about logic or science and there is really no point
arguing in this scientific age. Take steps in practice and
experience the truth of Buddhas words. Of the 3 dharma seals, the
truth of suffering to me is most difficult to experience in
depth.
May all take Buddhas words seriously."
