The Quran is the Book of God. It has been preserved in its entirety for all time to come. The Quran is apparently in the Arabic language, but in reality, it is in the language of nature, that is, the language in which God directly addressed all human beings at the time of Creation. This divine invocation of humanity is ever-present in the consciousness of all human beings, that is why the Quran is universally understandable to some on a conscious plane, and to others at the subconscious level. This reality has been described in the Quran as 'clear revelations in the hearts of those who have been given knowledge.'
