Now, here's a conversation worth having! The nature of being.
I first want to highly recommend to you a writer named Ken Wilber. This prolific genius does the best job I have encountered resolving religion vs science. One of his points - and this is key - is that the world we think we live in is, by definition, a function of our own perceptual origins. That is to say, we develop in our consciousness from the moment we are born. And the unconscious assumptions we make about identity absolutley define what we see.
In the West around the time of the Renassiance we in the West divided science, spiritual inquiry and creativity into separate buckets. For better and for worse.
Wilber argues that the scientific injuntion, boiled down into its essence is: do this action, observe with these tools, and see for yourself whether you confirm the same findings. He asserts that subjectivity, can be an observational tool, if the reported findings are commonly asserted.
He (along with many, many others) observes that throughout history and in all cultures, people who undertake certain, essentially common practices to develop their consciousness (which, being accomplished, have global impact on the personality) and all report essentially the same findings. Eureka, there is a fundamental truth to being.
Take the concept of faith. This is a fundamental psychological reality in all major wisdom traditions. It's not necessarily bound to a very difficult concept like "Jesus was the only son of God and only through accepting that idea does one go to Heaven." It is a condition of mind and spirit, and in fostering it, one accesses joy, generosity, and makes peace with one's own mortality. These are conditions of mind and spirit which cannot be artificially manufactured. One must work diligently, with self honesty to attain. There are no "tricks" to the process.
Or let's look at prayer. There is a writer, Larry Dossey - a physician. Now, he divides the concept into 2 basic approaches: one is the sending of requests to an outside agency (God) who then acts or does not act. The second is the concept that there is no sending of energy somewhere - that the nature of reality is not linear like that and that there are "non-local" connections made through meditative states. He quotes enormous amounts of research - some compelling, some not so compelling - that support this second concept's validity.
One of my best friends was diagnosed with kidney cancer. Surgery to remove the kidney occurred about 4 weeks after diagnosis. In the intervening time, prayer of the second sort was undertaken by many people. When the kidney was removed, the cancer had died. True story.
The point is, there are two factors to consider regarding spiritual truths: one, where are you in your own development - what are your core assumptions about things, how honest are you in examining these, and two, what are the commonality and differences between a local wisdom tradition and other major inquiries into existence. For those who are certain their tradition is the one and only way, I already know I will not dissuade them. But for those who question....
