Kindness and kind deeds are a general category that include many individual mitzvot like charity, marrying off a poor girl, visiting the sick and comforting mourners.
Truthfully, the potential for kind deeds is immeasurable. Anything one does for his fellow man, even offering a single kind word, is part of the kindness that builds the world.
