O thou who seekest the Kingdom of heaven! This world is even
as the body of man, and the Kingdom of God is as the spirit of life. See how
dark and narrow is the physical world of man’s body, and what a prey it is to
diseases and ills. On the other hand, how fresh and bright is the realm of the
human spirit. Judge thou from this metaphor how the world of the Kingdom hath
shone down, and how its laws have been made to work in this nether realm.
Although the spirit is hidden from view, still its commandments shine out like
rays of light upon the world of the human body. In the same way, although the
Kingdom of heaven is hidden from the sight of this unwitting people, still, to
him who seeth with the inner eye, it is plain as day.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
