Language is only a barrier, emotion connects us all, the emotion of love and caring, those things lead to a happy mind. So do I think that language is used for thoughts, yes and no. We just know words to understand each other on a basic level, but to understand humans and animals on an emotional word- free level is so liberating. Most people have pets.. and many can’t deny the connection and understanding with these creatures. I feel that thoughts are emotion based. 🙂

This is just my opinion on the subject.
Have a beautiful day.
