Sorry about that basic assumption on my part, everyone. Yeah, Salty explained it perfectly. A "Kind" bingo worth one point means you've found the 3 different Kind spirits — young, old, and ancient, so you'd have 3 across — a bingo. A Young bingo would mean you found all 7 different types of Young spirits — kind, jealous, wrathful, evil, etc. So, you'd have 7 down worth 6 points.
You cannot get a bingo from an individual spirit. You need to complete all the squares in a given line — across or down.
