First of all, Starbuck, welcome, and hello to you! Nice to meet you.
The "purpose" of Buddhism if you like, is to see that Life contains Suffering, and to Eliminate that suffering.
'Suffering' is a bit of a contentious word, of course, because the original Pali word is 'Dukkha' which can be used - and translated - to indicate many states.....
it has variously also been translated as:
'unsatisfactory', 'stressful', 'difficult', 'fluctuating', �variable�, 'frustrating', or even just 'changeable'
But we tend to use the word 'suffering' because in essence, we do tnd to do this to ourselves!!
As to whether Buddhism is 'your own Path to Enlightenment' also depends a bit on which tradition you follow, but don't worry about that for now....It took me around 12 years to commit to Buddhism, and Take Refuge, and quite a few more besides, until I decided which Tradition I felt most drawn to....!
'Test-driving' is a little bit of a misnomer.
What the Buddha requests we do, is to take any teachings we find (not only Buddhist.....) and learn them, study them, examine them, investigate them, and really see whether the truth of them makes sense to us.
If they are logical, and we understand them, so we should commit to accepting them, but only on the basis that we completely agree with them and see the logic.
If something simply does not sit well with us, and we disagree completely, then we have a right to reject this - bearing in mind, and respecting, that others - contrary to what we have discovered for ourselves - do accept them, and live by them. We should never condemn or criticise anyone for this.
When we find something that is an enigma and we simply can't get our heads round it, then it's OK to leave it to one side, and simply deide to come back to it later. maybe then, we will have 'moved on' enough in other areas, to be able to tackle it. but it doesn't matter.
Things like Re-birth fall into this category. The Buddha speaks of Re-birth, and other matters in a quite definite manner, but even some very experienced Buddhists find some of the concepts difficult to study.... So it's ok to say "I don't know, and I maybe never will", because we can't 'Know' everything for sure - !
Once we have learnt, understood and accepted the Teachings of the Buddha, we have to commit to living by them, and practice them in our lives, on a daily, hourly, constant basis, and see for ourselves whether they are indeed the fulfilment of what we investigate.
It's called Folloowing the Path (or walking the Talk!)
Your first port of call, (if you haven't already touched on this) is to study the
Four Noble Truths , and the
Noble Eightfold Path , which are underpinned and supported, and partnered by the
Five Precepts.
This Link will also help you and be very informative.
I would suggest you save this website and dip into it ocasionally with any questions you might have....
And always, but always come back to us for any support we can give you!
