As a matter of issue I can see the necessity for Bodhisattava commitment as means.
But...if bodhisattava is taken in a certain way to exculsion....
The teacher buddha was considered to be approached by a being called Mara, Some take this mara to be a representation of obstruction itself, others take this as real being.
Now if real being is endeavored, that being present at all times and in many shapes and forms, one being, whose chief responsibility it be, that none escape, and none change things....why then that doing?
The only explaination as I see it is the connection between us and other beings perhaps of another sort, which we don't naturally perceive.
If creatures do exist, that eat human emotion/faulted aware conception(preferred that), as we may eat food, must be those human, not allowed to escape rebirth, and for their sustainance must be the most amount of humans possible, in any place.
WEll why then would we suppose they eat us human, emotions/awareness....a being that had cause and concern with us human, that we never escape, how then that could not be
its purpose. EAting of course in a aware sense, amounting to growing, that which is bigger, better, and perhaps with concieved eternal aspect. Such is the essential of eating a thing to maintain perceived, continuance.
So the way of things could be maintained only if that be the situation...humans are eaten....as means for concieved eternal sustance.
ONly then could such a thing as no excape be so so important to a being, like a mara, that any means be employed, that even one, did not do that,(escape), and that certainly one who did that, first they did not teach,and then, that their teacheings be corrupted as soon as possible, if one did escape and teach.
So if that is found.... any belief that holds to seeking a rebirth as human, more humans in any fashion, would be with the intention of the azuras.
A class of beings (though the name is arbitrary) that would eat such thing as human to continue a perceived eternal state.
So I would say on that basis any tradition calling for that thing(I don't know if any are as I know not any tradition)....would be one of question.
Do Tulkus on rebirth generally say...this is it, I have attained my rebirth, and will now work at this thing....generally; I say they do not seem to do that....reconsideration of path is most common. Not dropping the path but seeking other things in it.
So those that may rebirth as human per example to help others...generally they seem to rethink that, after that is done.
A personal opinion certainly, and perhaps many may consider it of no relevence but perhaps a bit it is.
How can we really qualify any tradition as good or bad or find final purpose to it without having it in our core.
WE don't have to stick our hand in a boiling pot to know it will burn us, but also we cannot know things of complexity without knowing their nuance.
So I could see that also on other basis....my answer being........... we shouldn't qualify other traditions but only our own. Perhaps only stateing what we find good in traditions not our own
Personally I am not buddhist and hold to no tradition getting most of my tools from Tibetan buddhism, a bit of mantra from pure land a bit of this and that from other. I am however not a dillitant in this, considering one tradition choice for tool of first choice being most important.
So qualify my answer as necessary.
But personally also I then find compassion naturally present, if any tradition did call for rebirth as human, I again would avoid that. As compassion seemingly need not that thing to progress in it or be found.
Less spiritual progression(perhaps) in deva or other realm but also perhaps less for them azura to eat.
And thusly with less eating.... less is the harm they then produce with advancing this thing so they may eat. HUman being perhaps preferred food it being so tasty their nuance and emotionality but other also eaten, all sentient being of solid form chosen....
So less(perhaps) spiritual progression.... but then also less harm.
I would choose that on the basis of less harm rebirth as human..... then be avoided at all costs that thing.
But no bodhisattava rebirthing as human to help human.....less harm by this way of thinking would preclude that.
Escape then as means of less harm being the only thing and way to end or deminish this thing. And
all and every effort exerted to accomplish that one thing...escape, as less harm it produces.
On such basis of compassionate intent one would be accomplishing and where one would end up would really not be all that important...as long as where one did end up one did not end up creating this singular notion of self which creates this thing they eat(azuras or those like them).
The idea one could return as human and really change a thing in a personal fashion, being a misconception.
I also then could be in a way signing my death warrent by saying such a thing in such a realm so dominated(or any number of bad occcurance so great their power be here)...but what matter that
mostly none would read nor consider it but again....what matter that....is that not by this thinking as this realm be
....idea of escape being the thing, so one remains and endeavors always, that thing, but never really taking a saw to those bars and escaping..... talking about remaining in prison, so one may teach other prisoners to escape.....seemingly faulted that, all then always teaching eachother but remaining in that place. That place the way it is constructed being harmful producing just by being in that place, that prison.
So there may be variance to this thing of tradition,if this be the case considered in this manner.
Then perhaps pure land makes as much sense as tibetan as zen or theravadan, or any other.
As escape, pure escape from this heinous domination of realm of azura, domination.... what tool we choose, hacksaw to cut bar, hiding in laundry basket, becoming member of work detail, and once out, running as fast as one can....not that be at all important in any fashion.
Not sawing on bar.......... seeing other hiding in laundry basket, saying...that is wrong,(how silly that)....escape by any or all means....that be the thing.
Perhaps one could take another, or a couple, in certain types of prison break out, but not more than that. Personally taking them with them.
It being finally considered to do such less harm always, when one escapes.
Once free........... one can then see what one can do to free others, inside not much one can do
Perhaps projecting video inside prision wall, if one has a certain type of video camera, or give them building plans of the prison, such as on internet,if they had a computer, or some other thing, If they are inclined to dig out....things on how one may escape........ things of that sort....who really knows or cares that thing...the present being before us now....
pure land tibetan theravadan zen whatever....hacksaw, laundry basket, work detail, or climbing wall.
Personally... I then now await them... saying now this thing in public..they knowing it not that they...be prisioners also.... of their eating. By freedom from imprisonment of any, be to their aid as well....eternal be they not....nothing they eat that may assure.
Ignorant they know that not.... as those they imprison know that not. They are the same.
I await them now and care not....escape it is the thing. Shot in escape, fall and break leg....escape it will be nevertheless, in any form or fashion...this thing be ended.......... this imprisionment.
FAst then imposed that thing, of tantric means, perhaps that thing...with the study of that thing,,of less to it then, perhaps they may know....their persistence in this thing...it is for naught. Nevertheless escape it is the thing. Less harm it certainly will bring. That cannot be denied in any form nor fashion.
And perhaps then that....why even one so escaping, it is so much to them. Fully, full to the brimm with food, never knowing that hunger to be, so obscure that so never considered that other..with the full is the not....one escape, a bit of hunger then, perhaps that is why even one, be so important to them...so they may not know that even once...a thing not eaten. Prisioners not knowing this thing to occur, (one perhaps then said simmply dead).. jailers by necesssity must know of that thing so others may not do as that one did. So they may be helped as well....rebirth as human... no. Not if choice is offered.
