वही दाना है कहा जिसने न माना दिल का vahii daanaa hai kahaa jisne na maanaa dil kaa

baad muddat ke ye ae 'daaG' samajh me.n aayaa

vahii daanaa hai kahaa jisne na maanaa dil kaa 

बाद मुद्दत के ये ऐ 'दाग़' समझ में आया 

वही दाना है कहा जिसने न माना दिल का 

I understood this after a long long time, o 'daaG' 

He who doesn't give into temptation  is truly wise

There is a whole lot of poetry urging you, in fact exhorting you to follow your heart. Allow your mind to guide you. The mind is a very dangerous thing to follow. It can go all over the place. And take you along. The poet here laments the fact that he has given into the demands of his heart for way too long.
