The world is continually proclaiming these words: Beware, I am evanescent, and so are all my outward appearances and colours. Take ye heed of the changes and chances contrived within me and be ye roused from your slumber. Nevertheless there is no discerning eye to see, nor is there a hearing ear to hearken.
- Baha’u’llah (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)
