Rumi's Masnavi - You have such an enemy as this in your inward part: he is the preventer of the intellect, and the adversary of the spirit and of religion.

You have such an enemy as this in your inward part: he is the preventer of the intellect, and the adversary of the spirit and of religion. 4055

دشمنی داری چنین در سر خویش ** مانع عقلست و خصم جان و کیش

At one moment he dashes forward like the Libyan lizard; then (again) in flight he darts away into a hole.

یکنفس حمله کند چون سوسمار ** پس بسوراخی گریزد در فرار

Just now he has (many) holes in the (human) heart, and from every hole he is putting out his head.

در دل او سوراخها دارد کنون ** سر ز هر سوراخ می‌آرد برون

The name that denotes the Devil's becoming hidden from (men's) souls and going into that hole is khunús (slinking back),

نام پنهان گشتن دیو از نفوس ** واندر آن سوراخ رفتن شد خنوس

For his khunús is like the khunús of the hedgehog: like the head of the hedgehog, he pops in and out;

که خنوسش چون خنوس قنفذست ** چون سر قنفذ ورا آمد شذست

For God hath called the Devil Khannás (the slinker), because he resembles the head of the little hedgehog. 4060

که خدا آن دیو را خناس خواند ** کو سر آن خارپشتک را بماند

The head of the hedgehog is continually being hidden because of its fear of the cruel hunter,

می نهان گردد سر آن خارپشت ** دم‌بدم از بیم صیاد درشت

Until, when it has found an opportunity, it puts out its head: by such a stratagem the snake becomes its prey.

تا چو فرصت یافت سر آرد برون ** زین چنین مکری شود مارش زبون

If the fleshly soul had not waylaid you from within, how would the brigands have any power to lay a hand upon you?

گرنه نفس از اندرون راهت زدی ** ره‌زنان را بر تو دستی کی بدی

On account of the exigent myrmidon, who is Lust, the heart is captive to greed and cupidity and bane.

زان عوان مقتضی که شهوتست ** دل اسیر حرص و آز و آفتست
