On the buddhist concept of Rebirth

[MelT]

Anywhoo, this was the belief the Buddha himself had on rebirth so far as I know. .

Yes, more or less. You have to be careful to think of it as expedient means. It's a relative understanding and not actually the full Buddhist view of what it is, but an intermediate teaching to help guide you towards the fuller meaning.

I think too it can be rather difficult to describe a certain aspect of buddhist philosophy, since almost all of them tend to relate to each other, and you must understand them all to completely understand one.

I'd say the opposite to be honest. Once you fully understand one you will understand them all.
