The schools emphasising in nirvana have a simple target: the meditator wants to elevate to the arahant level and there to remain. But the next level of the way is beyond the ability of the arahant. You cannot find the way outside of your self. So the attitude "holding nothing will allow nothing to rise" still creates karma, and as such is a product of a ...[text shortened]... n, on your own.
You know that all return to One; can you tell me where the One returns?

And with Zen there's definitely a focus on not worrying about holding that attitude- how can wanting to achieve nirvana actually get you there if you're holding onto expectations and desires to reach it? It's kind of a catch 22 and when Buddhism adapts the more naturalistic and animistic ideals of Shintoism and Confucianism it almost tries to alleviate this stress.
Basically we trap ourselves in our pursuit for our goal (in this example, nirvana) and that's just an inherent nature and that in itself is part of nirvana because we are doing things unforced (wu-wei?). It's you working the way you are.
I think the directive in these schools is a constant progression- become more aware and aligned with your found morality and continue to grow. And I also think that you're paradise and hell is all in front of you and it's how you manipulate the things around you (perspectives and actions) to highlight it.
Edit: Referring to your last question- And i don't hold that as a preoccupation of mine to wonder where one will return to. I can't know and so there's no point in going on anything beyond skeptical speculation. After all, this is an issue people will hold distaste in their hearts amongst each other and wage war
