If you find you need to visualize someone when you pray,
think of the Master. Through Him you can address Bahá'u'lláh. Gradually try to
think of the qualities of the Manifestation, and in that way a mental form will
fade out, for after all the body is not the thing, His Spirit is there and is
the essential, everlasting element.
- Shoghi Effendi (From a letter dated
January 31, 1949 written on behalf of Shoghi Effendi to an individual believer;
The Compilation of Compilations, Vol. II, The Importance of Prayer, Meditation
and the Devotional Attitude)
