The obligation to repent

Hi,

"Mitzvah 73 is that Gd instructed us to admit sins of desire and accidental sins which we have committed before Gd, and to declare them, along with our repentance. This is called viduy, and it means that one should declare, 'Please, Gd, I have sinned accidentally, I have sinned out of desire, I have sinned out of rebellion, and I did such-and-such.' One should go on at length and request forgiveness in this manner, according to his speaking ability."

(Rambam, Sefer haMitzvot, Aseh 73)

Have a great day,
Mordechai
