Quran is not the book of verses but it is the book of signs (آيات) which contains established (ٱلْمُسْتَقِيمَ) road maps (ٱلصِّرَٰطَ) for the agitated minds (الناس). The entire theme and context of the book Quran is human mind. One of the meaning of nafs نفس is human mind or psyche.
The truth is we all unknowingly serve and seek help from our own knowledgeable mind or the universal conscious mind (رَبِّ ٱلْعَـٰلَمِينَ) - The right guidance for the right path is also given provided we serve our conscious mind properly.
إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ
ٱهْدِنَا ٱلصِّرَٰطَ ٱلْمُسْتَقِيمَ
We will never understand the book Quran if we study it in the context of human history or history of "The Biblical or Islamic Prophets" or in the context of "Heavenly God."
