Behavior-Giving one’s parents Nachas from one’s actions and behavior between man and man and between man and G-d:
Included in the mitzvah of honoring one’s parents is for one to endeavor to follow the correct path of Torah, mitzvah’s, ethics, and behavior between man and his fellow in a way that he is pleasing in the eyes of man and heaven, as this is the greatest honor that he can give his parents. [Likewise, following in the specific footsteps of one’s parents and ancestors in their approach in service of G-d, is included in the Mitzvah of Kibbud Av Vaeim. Thus, a Chassid should learn and spread Chassidus as was the will of his ancestors.]
Not to transgress G-d’s commands: A child who transgresses a command of the Torah or even of the sages, and by doing so causes his parents to become ashamed, transgresses the biblical prohibition of honoring his parents.
