With me thy eager search to aid Be every hill and cave surveyed. Great chiefs like thee, the best of men, Endowed with sense and piercing ken, Though tried by trouble never fail, Like rooted hills that mock the gale.”

In plain words: Lakshmana says they should search every hill and cave together. He tells Rama that great people like him, wise and sharp-sighted, do not give up in hard times, but stand firm like mountains in a storm.
