Truth is an Absolute, Transcendent Unity. Sounds are created out of Sound by the Universal Sound (called Logos by the Christians) which penetrates the mind-mesh giving rise to all particular sounds. Particular sounds show the existence of Universal Sound but do not explain it.
This Universal Truth is Universal Sound and not Silence. It is active, it is Life, yet in a certain sense it is changeless above and including all change. Human speech comes into existence by the grasping of the rays of Universal sound by the mind-mesh, but none of such utterances can either be or describe the Universal Sound which is Truth. A chicken cannot be described by the eggs she hatches, yet it is natural for the chicken to lay eggs. Yet human speech, through the praising of God, causes a turning back to God. This is through the process of renunciation (not abolition) of thought and speech. Through such a process one becomes one with Truth, and Truth is reflected in speech and is the cause of speech but of itself it is not speech.
