The Hidden Words is written in the form of a collection of short utterances. Bahá’u’lláh has taken the essence of universal spiritual truths and written them in brief form, thus providing a distillation of the spiritual guidance contained in the successive Revelations of God.

The themes of The Hidden Words include justice, purity of heart, turning to God, humility, detachment, life after death, sacrifice, unity, the nobility of the human being, selflessness, the importance of spiritual sight, and many others.
