Similar in Malayalam. Lots of romantic songs translated literally would have "my liver" (കരൾ, karal), instead of "my heart" for example.

Also in Turkish. "Canım ciğerim" (my beloved, my liver) is a term of friendly affection. Also when we want to say something like "I know what kind of person you are and what you are up to!" we say "ciğerini bilirim" which literally means "I know your liver" / "I know how your liver is like". One more: "ciğersiz" (liverless) is an insult for a person who wrongs you, schemes behind you, does not help you when you are in need, ungrateful etc.

In norwegian we use the phrase “snakke rett fra levra”(speaking from the liver). It means you’re speaking your honest opinion.

I speak hindi and never realized that's what jigar means! Always just assumed it was another word for heart or soul.

Same in Persian. I didn't know the difference between jigar and kaleja. Looks like kaleja is of Sanskrit origin while jigar is of Persian origin.

When you use kaleja in that phrase, it means heart.

The Malay/Indonesian “hati” is the same.
