Übersetzung - Russisch-Englisch - Живу сердцем.

@Aneta

It's "(I) live with (my) heart", though pronouns are ommitted.

@expert

The meaning roughly is "I live by means of my heart".
"With" doesn't mean "together", it's the same to "I write with my hand or see with my eyes".

Ooops! You're right. I don't know why I translated it in the imperative. Perhaps it was the similarity to ancient Greek what confused me...
Thank you, Siberia.

I live following my heart

I think everybody lives with his/her heart, but here probably it should be translated as "I live listening to my heart"

Well, I think some rely on there mind mostly. Request says quite the contrary as previous two posts try to describe.
