Hello there 
In mahasatipatthana sutta there is repeadetly a very important sentence (Ajahn Sujato translation)
https://suttacentral.net/dn22/en/sujato
Or mindfulness is established that the body exists, to the extent necessary for knowledge and mindfulness. They meditate independent, not grasping at anything in the world.

Being translation of:
āAtthi kÄyoāti vÄ panassa sati paccupaį¹į¹hitÄ hoti yÄvadeva ƱÄį¹amattÄya paį¹issatimattÄya anissito ca viharati, na ca kiƱci loke upÄdiyati.
etc. etc.
Could you please tell me which part of this pali sentences mean just this:
They meditate independent, not grasping at anything in the world
without the rest part of the sentences?
It is importaint to me, because I donāt know pali, but I think it would be great to have few most importaint pali references in my paper, so the reader can get this āfeeling of original teachingā regarding most important parts. And framework Iāve taken is a path of progressive not grasping, thatās why this sentence is so importaint.
I believe this is also one of most fundamental sentences in the whole pali canon, so it would be great to have it one short sentence 
Sorry for asking so many questions, I promise to limit myself.
With metta
It rhymes beautifully
