"everything their hearts wanted to think about"

# the thoughts of their hearts

The writer speaks of the heart as if it were the part of the body that thinks. Your language may use a word other than "heart" to talk about the part of people that thinks. Alternate translation: "their inner, secret thoughts" (See: [[rc://en/ta/man/jit/figs-metonymy]])
