Though we have not arrived yet at the third stage, and we have still not had enough time to develop, this does not detract from our essence. That is because the third stage follows inevitably from the first stage, and [to paraphrase a talmudic principle,] “a debt that stands to be collected is [considered] as if it were already collected.” Not having had enough time to develop is only a problem if there is a doubt about whether the process will fully develop to perfection in the time available.
And since we have no doubt about that at all, [since developing from stage one, to two, to three is inevitable], it is as if we have already achieved the third stage. The body that was given to us for now, with its problematic form, does not damage our essence, since it [the body] and everything it acquires will be completely eliminated together with the source of impurity. And “anything that will inevitably be burnt is [considered] as if it is already burnt” (Menaḥot 102b) and as if it had never existed.
