Hum there are a lot of ways to think about correct feeling, from how my own body feels for things like quality of my structure, how relaxed I am, how I feel the connection to my partner or attacker, as well as how much of their structure and center I can feel.
I have found that expecially for beginners the link below on "Aikido from the Inside Out - The principals" gives a good initial perspective on all those components of correct feeling as I understand them
