Aşk acısını taşımayan yürek;
Ya deliye aittir, ya ölüye!.
O, bensizliği göze aldıysa, Ben onsuzluktan bir şey kaybetmem!...
Bakışlarında diyar diyar gezdiğin değil,
Bir bakışıyla diyarına gittiğindir AŞK!.

My Try:

The heart that doesn´t carry pain of love

belongs to an insane or a dead person.

If he didn´t see any problem in being without me I won´t lose a thing because of being without him.

You don´t pass love looking at it like country after country

but you enter its country by looking at it just once.

(Very unsure of the last lines, wait for someone else to check it.)

My try for the last two lines ;

Bakışlarında diyar diyar gezdiğin değil,
Bir bakışıyla diyarına gittiğindir AŞK!.

Love is not something that

you travel from one land to another in her/his look [eyes]

but it is something that

[makes]you travel into her/his very land

by her/his single look.

Sometimes you need a sixth sense to distinguish [POSS sg 2nd ] from [POSS sg 3rd + pronominal -n- ]. I don´t have it. Another problem is to decide when the 3rd person refers to a definite ´someone´ and when to the tragedy of life in general.

Thanks for the correction, tunci.
