There is a concept in Halacha called, לאו שאין בו מעשה. This refers to a large number of Torah commandments that are forbidden but do not carry with them, an action. As such, the punishment for such infractions are given in Heaven, and not by an earthly court.
Of the 365 negative commandments, 207 are punishable with lashes.There are a number of others, that are considered very severe, where either the punishment is Kareit or a death penalty. The rest fall in the category of לאו שאין בו מעשה.
Some examples are the following: There is a לאו that we must not forget Hashem. The Torah says, הזמר לך פן תשכח את ה׳ אלקיך, “Guard yourself lest you forget Hashem your G-d.” We are to remember Hashem at all times. We are to try to acquire for ourselves those traits that allow us to remember. We do this with proper thoughts, modesty, fear of Hashem, and working on our Midot.
Lashon Hara, not taking revenge, hating another Jew, and being hard-hearted with the poor, are all under the category of לאו שאין בו מעשה. More examples to follow tomorrow, G-d willing.
