As a secular meditator I would prefer not to make the assumption that Buddhist metaphysics is correct.
I would like to see the creation of a kind of mindfulness meditation informed by secular western developments such as the phenomenology of Husserl and Heidegger for example.
I think that while the experiences of meditators and shamans of different traditions are genuine, in order to describe and systematize these experiences, they have to rely on the cognitive, social and philosophical resources of their time and place.
The experience might be eternal, but the material of understanding and explication is historical and tied to all kinds of hoary assumptions which often pass without examination.
The critical tools of modern philosophy and continental philosophy in particular can be extremely helpful for the meditator.
The critical tools of modern philosophy has been disconnected from direct experiences for this, so it's not as useful as you think it is. At least, not until you have direct realizations.
Where I've found them useful is when (1) you experience said insights, (2) you're off the cushion and trying to integrate them into your daily life and habits. I've also found that " they have to rely on the cognitive, social and philosophical resources of their time and place." is not as big of an influence as you think it is. (And the reverse is true: you experience how modern critical tools have their own built-in biases). But if you have not had experienced for yourself, then I'm not going to be able to persuade you to that view.
I would love to hear philosophers frame these experiences having first experienced these themselves. Otherwise, there's no point. I am, in fact, going to engage a philosophy friend in a discussion after he participates in a few shamanic ceremonies. That will be interesting.
I think if meditators were to study continental philosophy in particular, they would find many fruitful parallels to concepts in Eastern thought. Phenomenology involves examination of arising phenomena in a similar fashion to mindfulness, though I don't think it is ever as clearly explained. There is within it an attempt to overcome the subject-object distinction, and to re-frame the relationship between scientific objectivity and the lived experience of the human life-world. Unfortunately it is also some of the most impenetrable stuff ever written!

I will take you up on that, but it might take me a few years. :)
I see this in all the wisdom traditions, so that includes a reading of Jewish, Christian, and Islam.
Check out Terrance McKenna some time if you haven't. There is in which he does a trialogue with Rupert Sheldrake and Ralph Abraham. While I don't precisely agree with some of McKenna's comments on religions, his works are excellent sources of questions. :-D
I think it is awesome you want to create a mindfulness practice informed by secular western developments. If you have a chance to participate in a (genuine) shamanic ceremony, your philosophical training will bring a lot to the experience. (There is a mind-to-mind phenomena you can observe in vipassana retreats or in shamanic ceremonies; the content of your mind doesn't just inform your experience, it also affects the collective. So when you bring your Western secular experience into the mix, it brings a, in my opinion, vital perspective into the experience).
I suggest that there is a allergy/aversion to religious traditions that should be investigated by a meditator at some point. Likewise, there are aversions to secular methods as well that needs to be investigated.
