It's really hard to translate a poem. And I wish you had posted a bit more of the context. Anyway here's my translation: من باید روشی را خلق کنم یا به اسارت(بردگی) روش فرد دیگری دربیایم. I don't exactly know what "system" means here. It could have a lot of meanings depending on the rest of the poem. I hope you find this translation helpful.
