To be given the opportunity to do teshuvah is an enormous privilege. It is a joy to be able to say I am sorry. This is the ultimate expression of religious optimism. Judaism teaches man that there is no karma that traps him, and no original sin that stands in his way. Man is free to re-engage with God and his fellow man. Whatever obstacles there may be, all that is required is the will to change his ways and the effort to work hard at it.
