अजोऽपि सन्नव्ययात्मा भूतानामीश्वरोऽपि सन्।प्रकृतिं स्वामधिष्ठाय संभवाम्यात्ममायया॥

Word by word
The verse says
Though I am unborn and do not decay, though I am the lord of what exists - I take up my own nature and come into being by my own power.
In plain words
Three concessions and then a contradiction, held in one line.
Unborn. Undecaying. Lord of beings. And then: sambhavāmi - I come into being.
Krishna is not resolving the tension. He is stating both halves.
Where you've felt this · in health
A doctor on the ward has had the illness she treats. Not one fact of her training has changed. Everything about how she sits down at the end of the bed has.
Going deeper
Ātma-māyayā - by my own māyā. This is the word doing the work, and it is one of the most misread words in Indian thought.
Māyā is usually rendered illusion, which pulls the verse toward a reading in which Krishna only appears to be born and the body is a kind of stage costume. Some traditions do read it exactly that way.
But the word more basically means the power to bring something about - the making-power, the art by which an appearance is produced. On that reading he is not pretending to be born. He is doing something, using a capacity that is his.
The traditions split here and the split matters. If the birth is only apparent, the avatāra is a display. If it is real, then something genuinely enters the conditions it came to change.
This edition does not resolve it, because the word supports both readings and the difference is a live one. What both share is the structure: the unconditioned takes on conditions deliberately. And the phrase beside it - standing on his own nature - suggests something occupied rather than faked.
