Lal:
It appears we were typing at the same time!
“Those are 14 jati, and not bhava.”
This had occurred to me. Still, as I see, the text allows for those 14 ‘lives’ to be bhavas not only jatis. For one thing ( or better for HALF a thing, in this case) bhava and jati mean the same in deva realms. (It is only ‘the small matter’ of the difference in duration between 7 and 49, at most, human jati!)
Please correct me if that is not so
