Repetition of something is necessary in order that we understand the matter thoroughly, without error.
This is of crucial emphasis, seeing as the remedy for the unconsciousness that is the fallen state of the soul and its fixation on the body and its pleasures, discounting the spiritual potency, is the spontaneous and consistent recitation of the Holy Names of the Lord. Deviating from the prescription for those who find themselves in darkness ensures the continuance of ignorance and a begrudgingly slow trip home back to the Spiritual Sky.
