You seem to have arrived at the classical concept of “the four loves”, referring to the four Greek words commonly translated as “love” in English:
στοργή :: natural, familial affinity
φιλία :: interest/enjoyment as coming from a free & rational agent
ἔρως :: craving for unity with what is “beloved”
ἀγάπη :: “to will the good of the other”
Somewhere I have old notes that link them together in a reasonable way, but I would have to dig that up later, if you would be interested.
It may be worth noting that traditionally, Jesus is depicted as being in agreement with Siddhartha here, having emptied Hades before exiting the tomb alive again. This is further emphasized in a sermon preached ~1600 years ago by John Chrysostom, and repeated every Easter in Orthodox (& some Catholic) churches, which includes the line “Christ is risen, and not one dead remains in the grave.” Though in combination with other beliefs about Hades/Hell, it seems the intended meaning is that everyone was/is given the option to “ascend”, but perhaps not everyone chooses to take it.
