In Poem 29 of Chapter 20 of Attar's Mokhtar Nameh, the poet contrasts the intense inner turbulence of the mystic with the outward silence of genuine piety. While the lover's heart experiences a 'thousand surges' like a restless ocean, true asceticism (zuhd) demands silencing the tongue. This silence signifies that the mystic's spiritual practice is deeply personal and sincere, rather than a performative act meant for public display or 'sale' (seeking worldly validation or praise).
