This has not been stated. It is not very logical, how can Contact upon which the delineation of Consciousness depends occur without Four Primary Elements having a footing? I do not understand why the need of bending over backwards when there exists a perfectly reasonable simple explaination.
Furthermore the way you read it raises several questions;
1) Why is it "without feature or signless".
Given that contact at a Sense Base has three constitutes, why exactly was this stated about Vinnana Anidassanam?
2) Why is it called "endless", "limitless" or "boundless"
Given that Consciousness of Aggregates is impermanent, this seems very important and demands an explaination.
3) Why is it refered to as a "place" much like a dimension? Note the question "Where?" and the answer "Here"
4) If it is to be read as you suggest, why has it not been stated?
5) The last part of cessation of concsiousness needs explaination.
How do you explain that with the cessation of consciousness there is consciousness?
6) Consider this;
That’s where earth, water, fire and air find no footing,
There both long and short, small and great, fair and foul -
There “name-and-form” are wholly destroyed.
With the cessation of consciousness this is all destroyed.’”
If we add your [cravings for] it reads;Viññāṇassa nirodhena etthetaṃ uparujjhatīti.
That’s where cravings for earth, water, fire and air find no footing,
There the cravings for both long and short, small and great, fair and foul -
There the cravings for “name-and-form” are wholly destroyed.
With the cessation of consciousness cravings for all this is destroyed.’”
That would mean that as long as there is Consciousness the craving is not destroyed?
Do we have a theory of Arahants having craving until the breakup of the Aggregates now?
