Rumi's Masnavi - Know that the nature of lightning is that it taketh away the sight; regard the everlasting Light as entirely Helpers (to the attainment of vision).

Know that the nature of lightning is that it taketh away the sight; regard the everlasting Light as entirely Helpers (to the attainment of vision). 1545

برق را چون یخطف الأبصار دان ** نور باقی را همه انصار دان‏

To ride (your) horse upon the foam of the sea, to read a letter in a flash of lightning,

بر کف دریا فرس را راندن ** نامه‏ای در نور برقی خواندن‏

Is, to fail, because of covetousness, to see the end; it is, to laugh at your own mind and intellect.

از حریصی عاقبت نادیدن است ** بر دل و بر عقل خود خندیدن است‏

Intellect, by its proper nature, is a seer of the end (consequence); ’tis the fleshly soul that does not see the end.

عاقبت بین است عقل از خاصیت ** نفس باشد کاو نبیند عاقبت‏

The intellect that is vanquished by the flesh becomes the flesh: Jupiter is checkmated by Saturn and becomes inauspicious.

عقل کاو مغلوب نفس او نفس شد ** مشتری مات زحل شد نحس شد

Still, turn this gaze (of yours) upon this inauspiciousness, look on that One who made you ill-starred. 1550

هم درین نحسی بگردان این نظر ** در کسی که کرد نحست درنگر

The gaze (of him) that surveys this ebb and flow pierces from the inauspicious influence to the auspicious.

آن نظر که بنگرد این جر و مد ** او ز نحسی سوی سعدی نقب زد

He (God) continually turns you from one state (of feeling) to another, manifesting opposite by means of opposite in the change,

ز آن همی‏گرداندت حالی به حال ** ضد به ضد پیدا کنان در انتقال‏

For the purpose that fear of the left hand side may bring to birth in you the delight of “He causes the (blessed) men to hope for the right hand side,”

تا که خوفت زاید از ذات الشمال ** لذت ذات الیمین یرجی الرجال‏

So that you may have two wings (fear and hope); for the bird that has (only) one wing is unable to fly, O excellent (reader).

تا دو پر باشی که مرغ یک پره ** عاجز آید از پریدن ای سره‏
