The closest equivalents are stin, staadnau, gaar and uznahgaar, all describing freedom or lack of restraint. Could you post the full quote you are translating?

Another close word would be bolaav "to grant".

 the whole sentence is "nothing is true, everything is permitted"

thanx XD

First draft: Nid los vahzen, pah los stin. "Nothing is the truth, everything is free/unrestricted".
