help clear the doubt.

Recently i was reading Bhagvad Gita when i came across a sentence in 2.20 saying : ” to kill someone’s body without permission is punishable (kunachyahi sharirachi adhikaaravina hatya karne nindaniya ahe ) “.
I am confused with the word ” permission “. Can someone please elaborate more on this and clear my confusion ..

Thanking you in advance.
