Ok to put it in the most basic way, it essentially grants you Freedom and Life Determination at absolute level. You transcend your origin so you decide your life, your origin, your self. You are not bound by any creator or origin so if a time travelers unalives your parent or past self, you won't work. You no longer are bound by such mere origins.

@Abdalla1234 Interesting. Why does it have Autopotence as an application? Consider me intrigued!

If you transcend your origin, you are Omnipotent over it. Like how Altair from Re Creators transcended fiction and Became Omnipotent over it (she is a main user of origin transcendence since fiction was her origin and she transcended it and Became real and no longer bound by her author and plot)

@Abdalla1234 Hold up. Origin Transcendence makes you omnipotent over your own origin?

Well should be since you transcend it.

@Abdalla1234 What differentiates it from Autopotence if you're omnipotent over your own origin?

It's not Autopotence, but it is a power that achieves it in its own way

@Abdalla1234 Intriguing! I shall remember that.

Basically you transcend your own origins for example you would transcend our universe since its where you were born thus you would transcend the laws of our universe

I disagree with @Abdalla1234 that it would make you omnipotent of your origin or even yourself just because you are not bound by it does not mean you can control it

It might not give you any control over the universe just makes you free from it
