English Translation (preserving Jain terms):
637. In that same infinite karmans, there are innumerable loka-prameya (infinite worlds) as the limit of the upward movement. 638. Similarly, in the least karmans, there are innumerable loka (worlds) as the limit of the upward movement. 639. Then, in the one loka-prameya upward, in the two loka-prameya upward, or in the infinite loka-prameya upward, those very same upward movement stations exist in the least karmans. 640. When one loka-prameya part is thrown away, the second upward movement station becomes the circumference. 641. The least projection in the least karmic body, and the least karmic second upward movement station distinction is innumerably multiplied. 642. Here too, there are innumerable upward movement stations.
Specific meaning - The meaning of the least karman suitable for the asabhya-siddhas (inauspicious liberated beings) is that the karmasaya (reservoir of karmas) jiva who remained in the ekendriyas (one-sensed beings) up to the karmasthiti (duration of karmas), and there accumulated the least karman, that is the least karman intended here for the asabhya-siddhas. From this least karman, the smallest upward movement station arises. In addition, Jaydhavala has also described the origination of the least upward movement station in another way. They say that the jiva who, with the least karman, was born in the asanjni-pancendriyas (unconscious five-sensed beings) after coming from the ekendriyas, and quickly bound the devayu (divine lifespan) and was born among the devas. There, after becoming paryapti (complete), he first attained upasama-samyaktva (equanimity-right faith), then adopted vedaka-samyaktva (cognition-right faith), and after maintaining vedaka-samyaktva for sixty-four sagaropamas (ocean-measure time periods), when only an antarmuhurta (moment) was left, he arose for the destruction of darsana-moha (delusion of viewpoint). At the final moment of his downward activity, due to the least disposition, the smallest upward movement station of mithyatva (false belief) arises through the bhuta-vidhyata-sankramana (transmigration of the past).
Now the description of the non-least upward movement station of mithyatva is being done.
Churni Sutra - In that very same meritorious karman, another upward movement station arises, which is more than innumerable loka-prameya (infinite worlds). Again, in that very same least meritorious karman, a third upward movement station arises, which is more than innumerable loka (worlds). In this way, in that very same least meritorious karman, there are innumerable loka-prameya upward movement stations. One more, two more, three more, four more, and so on, in the order of countable more, innumerable more, and infinite part more, those very same upward movement stations arise in the least meritorious karman. (This is the first series or sequence of upward movement stations.) When one loka-prameya part is thrown away in the least meritorious karman, the second series of upward movement stations arises. The distinction of the second upward movement station in the least karmic body, i.e., the least projection, is innumerably multiplied from that. In this second series of upward movement stations too, there are innumerable loka-prameya upward movement stations.
