Without words we speak, we communicate, we converse with God and hear the answer....

All of us, when we attain to a truly spiritual condition, can hear the Voice of God.

(from a talk reported by Miss Ethel J.Rosenberg).
Baha'u'llah declares that the higher spiritual truths can be communicated only by means of this spiritual language.

The spoken or written word is quite inadequate.

In a little book called The Seven Valleys, in which He describes the journey of travelers from the earthly dwelling to the Divine Home, He says, in speaking of the more advanced stages of the journey:-- The tongue is unable to give an account of these, and utterance falls exceedingly short.
