'Undisturbedness' in the Bible

Grace to you and peace [inner calm and spiritual well-being] from God our Father and the Lord Jesus Christ.

And the seed whose fruit is righteousness (spiritual maturity) is sown in peace by those who make peace [by actively encouraging goodwill between individuals].

“He must turn away from wickedness and do what is right.He must search for peace [with God, with self, with others] and pursue it eagerly [actively—not merely desiring it].
