In Book One, Section 146 of the Masnavi, Rumi employs the figure of the Prophet Noah to illustrate the Sufi concepts of Fana (annihilation of the ego) and Baqa (subsistence in God). Noah warns his rebellious people that his human form is merely a veil (roopoosh); having died to his human ego and senses, God has become his 'hearing, perception, and sight.' Rumi connects this directly to the preceding fable of the Lion, Wolf, and Fox by having Noah describe himself as a hidden divine Lion within a seemingly weak human exterior. Noah cautions that to contend with him is not to fight a mortal man, but to challenge divine wrath itself.
