What does "past" mean here? [closed]
Solution 1:
past as used here is a preposition. And like prepositions do, it shows in what relation the first noun bliss (or equivalently, the pronoun that) stands in relation to the second one (the gerund bearing here).
past in this sense is defined as—
Beyond the power, scope, extent, or influence of
[American Heritage Dictionary]
Solution 2:
I believe "past bearing" here means - "beyond bearable".
The first definition is a better fit here, though it makes sense when you take the whole phrase into consideration.
