Rumi's Masnavi - When pure (lawful food) turns to impurity in your stomach, put a lock upon your gullet and hide the key;

When pure (lawful food) turns to impurity in your stomach, put a lock upon your gullet and hide the key;

چون که در معده شود پاکت پلید ** قفل نه بر حلق و پنهان کن کلید

(But) any one in whom morsels of food become the light of (spiritual) glory, let him eat whatever he will, it is lawful to him.

هر که در وی لقمه شد نور جلال ** هر چه خواهد تا خورد او را حلال‏

Explaining (that there are) some assertions the truth of which is attested by their very nature.

بیان دعویی که عین آن دعوی گواه صدق خویش است‏

If you are my soul's familiar friend, my words full of (real) meaning are not (mere) assertion.

گر تو هستی آشنای جان من ** نیست دعوی گفت معنی لان من‏

If at midnight I say, “I am near you: come now, be not afraid of the night, for I am your kinsman,”

گر بگویم نیم شب پیش توام ** هین مترس از شب که من خویش توام‏

These two assertions are to you reality, since you recognise the voice of your own relative. 3575

این دو دعوی پیش تو معنی بود ** چون شناسی بانگ خویشاوند خود

Nearness and kinship were (only) two assertions, but both (of them) were reality to the good understanding.

پیشی و خویشی دو دعوی بود لیک ** هر دو معنی بود پیش فهم نیک‏

The proximity of the voice gives him (the hearer) testimony that these words spring from a near friend;

قرب آوازش گواهی می‏دهد ** کاین دم از نزدیک یاری می‏جهد

Moreover, (his) delight at (hearing) the voice of his kinsman has borne witness to the truthfulness of that dear relative.

لذت آواز خویشاوند نیز ** شد گوا بر صدق آن خویش عزیز

Again, the uninspired fool who in his ignorance does not know a stranger's voice from a kinsman's—

باز بی‏الهام احمق کاو ز جهل ** می‏نداند بانگ بیگانه ز اهل‏

To him his (the speaker's) words are (mere) assertion: his ignorance has become the source of his disbelief; 3580

پیش او دعوی بود گفتار او ** جهل او شد مایه‏ی انکار او
