देवा भवित्ताण पुरे भवम्मि, केई चुया एगविमाणवासी । पुरे पुराणे उसुयारणामे, खाए समिद्धे सुरलोगरम्मे ॥१॥
Having been gods in a former existence, some who fell — dwelling-together-in-one-divine-abode — were born in the ancient, renowned, prosperous city named Ishukar, as beautiful as the realm of the gods.
In their previous existence, six souls had lived together in one divine abode (a single vimāna in the heavenly realm). Upon exhausting their divine lifespan, they were born together in the ancient, renowned, and prosperous city of Ishukar — described as beautiful as the divine realm itself. The sutra opens mid-story, establishing that these six souls are not random strangers: their joint heavenly life created a karmic bond that pulls them together again in human form. The phrase egavimāṇavāsī — "dwelling in one divine abode" — is the seed of the entire chapter; shared merit, shared past, and now a shared opportunity for liberation.
The simple version: Six souls who had lived together as gods in the same heavenly home were born again together in a city called Ishukar — because their past connection pulled them back to each other.
