In Book 1 of Rumi's Masnavi, the story of the grammarian and the boatman serves as a powerful allegory contrasting intellectual pride with spiritual survival. The grammarian, representing scholars obsessed with theoretical knowledge (Nahv or grammar), mocks the unlettered boatman. However, when a storm threatens to sink the ship, the grammarian's academic expertise proves useless. Rumi teaches that in the turbulent ocean of divine reality, what is required is not grammar (Nahv) but self-effacement and spiritual annihilation (Mahv). Survival depends on the practical wisdom of shedding one's ego to 'swim' in the sea of truth.
