In Chapter 17, Poem 5 of Attar's Mokhtar Nameh, the poet emphasizes the Sufi principle of concealing divine mysteries (sirr) after attaining spiritual knowledge (ma'rifat). Using the metaphor of drinking the 'wine of spiritual knowledge,' Attar warns the seeker not to casually reveal these profound secrets to the uninitiated. He contrasts the noisy, superficial babble of a 'mountain spring' with the deep, silent stillness of the 'ocean.' The concept suggests that true spiritual maturity and vastness are achieved through silence and internalizing the divine experience rather than boasting or speaking excessively about it.
