deeply care, whatever you desire

The now commonly-used German expression Herzenslust, which today is especially used in the phrasing “nach Herzenslust,” meaning to do something just like one wants (literally “follow the desires of the heart”), was first coined in 1534 in the German Bible translation by Martin Luther. (Source: Günther 2017, p. 77)
