user13084: I've been reading up on cosmology and am curious if Lord Suyama of Yama heaven and Lord Yama as judge of the recently deceased are the same figure. The latter is often said to reside in either the hell or preta realms, but since he is also a vaimanikapreta, I can't help but wonder if his time in the higher planes equates to this third level of heaven. Or are the same names simply coincidence?
Any thoughts/sources are much appreciated.

user10100: It is in the dependent origination.
SuyamaDeva born by KusalaVipakaCitta, wholesome resultant, only. That citta is the resultant consciousness, viññāṇa, of the wholesome frabrication, sańkhaāra.
YamaVemanikaPeta born by AkusalaVipakaCitta, unwholesome resultant, only.  That citta is the resultant consciousness of wholesome frabrication.
They are completely different.
Only one karma creates all life-basis-resultants  (patisandhi, bhavanga, cuti, karmaja-matter) per each rebirth of one whole life however there are many karma cause the resultant citta at the other six senses of life, except those patisandhi, bhavanga, cuti, which created by only one same karma.
