Verse 27

27. The birth of the existent is indeed reasonable through Maya, but not in reality. For whom that is, in whose opinion, is born the existent in reality, for him, that is, he would have to admit, indeed the already born is born!

The unity of the Primal existence of the eternal Singularity, the Absolute, means that Existence Alone is Absolute. That Truth means there is no further true birth. There cannot be another new existence.
The perception of entities coming into existence or being born is accepted through the reasoning of Maya. That is, entities that are perceived coming into being are declared through the process of logic and the understanding of Maya to be ultimately unreal.
Existence being an Absolute Unity, if one were to consider that Absolute to have been born even accepting the illogicality of that the fact would remain that the existent now exists so again there remains no more true birth.
