Infinite rebirth, finite kamma? If we have been transmigrating in samsara infinitely via rebirths, then doesn't that mean that kamma which we have earned too is infinite? And if so, doesn't that imply that enlightenment is imposible to reach since it would take one infinite amount of time to reach? I know this is classified as something that is unconjecturable and drives one insane, but this one is driving me curious. Any takers on this?
According to this Jainpedia page on Jain teachings on karma:

The karmas accrued over a lifetime trap the soul in the cycle of
births. The karmas mature by affecting the soul or the physical body
of its next lifetime or birth. When the body dies, the soul is born in
a different body, which is shaped by karmas from the previous birth
and the ones before that. The condition of the soul in that lifetime
is also influenced by karmas from previous incarnations. This cycle of
birth, death and life repeats endlessly while the soul has karmas
attached to it.
The soul yearns to fulfil its true nature, which it cannot do while it
is imprisoned within the cycle of rebirth. Only a soul without karma
can be liberated from the cycle of birth, reaching self-realisation.
Following the teachings of the Jinas and developing spiritually lead
to the prevention of new karmas entering the soul – saṃvara – and the
removal of existing karmas. ....
Destroying karmas that are attached to the soul requires ascetic
practices such as fasting, meditation and denying bodily needs and
comforts.

In MN 101, the Buddha debunked the following teachings of the Jains:

All the happens to a person is due to past karma
Elimination of past karma is possible by penance
Elimination of karma is possible by not accumulating new karma
With emptying of all past bad and good karma, suffering would end

In other words, the Jain way is emptying the karma account in order to end the cycle of rebirth, which is suffering.
The Buddha's path is that of the purification of the mind to end suffering, and not emptying of the karma account.
The Jain idea is that suffering is sustained by karmic balance. The Buddhist teaching is that suffering is sustained by craving and ignorance.
From MN 101:

“Mendicants, there are some ascetics and brahmins who have this
doctrine and view: ‘Everything this individual
experiences—pleasurable, painful, or neutral—is because of past deeds.
So, due to eliminating past deeds by mortification, and not doing any
new deeds, there’s nothing to come up in the future. With nothing to
come up in the future, deeds end. With the ending of deeds, suffering
ends. With the ending of suffering, feeling ends. And with the ending
of feeling, all suffering will have been worn away.’ Such is the
doctrine of the Jain ascetics.
I’ve gone up to the Jain ascetics who say this and said, ‘Is it really
true that this is the venerables’ view?’ They admitted that it is. ...
But since you don’t know any of these things, it’s not appropriate for
the Jain venerables to declare this.’  ...
Such is the doctrine of the Jain ascetics. Saying this, the Jain
ascetics deserve rebuke and criticism on ten legitimate grounds.
