True peace and tranquillity will only be realized

 

Say: O children of dust!
He Who is the Spirit of Purity saith: In this glorious Day whatsoever can purge you from defilement and ensure your peace and tranquillity, that indeed is the straight Path, the Path that leadeth unto Me. To be purged from defilement is to be cleansed of that which is injurious to man and detracteth from his high station – among which is to take undue pleasure in one’s own words and deeds, notwithstanding their unworthiness.
True peace and tranquillity will only be realized when every soul will have become the well-wisher of all mankind. He Who is the All-Knowing beareth Me witness: were the peoples of the world to grasp the true significance of the words of God, they would never be deprived of their portion of the ocean of His bounty. In the firmament of truth there hath never been, nor will there ever be, a brighter star than this.

The power of reflection.

 

Arts, crafts and sciences uplift the world of being, and are conducive to its exaltation. Knowledge is as wings to man’s life, and a ladder for his ascent. Its acquisition is incumbent upon everyone. The knowledge of such sciences, however, should be acquired as can profit the peoples of the earth, and not those which begin with words and end with words. Great indeed is the claim of scientists and craftsmen on the peoples of the world.
O people of Bahá! The source of crafts, sciences and arts is the power of reflection. Make ye every effort that out of this ideal mine there may gleam forth such pearls of wisdom and utterance as will promote the well-being and harmony of all the kindreds of the earth.

 Bahá'u'lláh,
Tablets of Bahá’u’lláh, p. 72

To whatever place We may be banished,

 

To whatever place We may be banished, however great the tribulation We may suffer, they who are the people of God must, with fixed resolve and perfect confidence, keep their eyes directed towards the Dayspring of Glory, and be busied in whatever may be conducive to the betterment of the world and the education of its peoples.
All that hath befallen Us in the past hath advanced the interests of Our Revelation and blazoned its fame; and all that may befall Us in the future will have a like result. Cling ye, with your inmost hearts, to the Cause of God, a Cause that hath been sent down by Him Who is the Ordainer, the All-Wise. We have, with the utmost kindliness and mercy, summoned and directed all peoples and nations to that which shall truly profit them.

Truthfulness and goodwill

The Daystar of Truth that shineth in its meridian splendor beareth Us witness!
They who are the people of God have no ambition except to revive the world, to ennoble its life, and regenerate its peoples. Truthfulness and goodwill have, at all times, marked their relations with all men. Their outward conduct is but a reflection of their inward life, and their inward life a mirror of their outward conduct.
No veil hideth or obscureth the verities on which their Faith is established. Before the eyes of all men these verities have been laid bare, and can be unmistakably recognized. Their very acts attest the truth of these words.
