In other words, it is more important to obey the commandments of God than to hold on to human traditions. Doing things because our parents and grandparents have done it exactly that way is meaningless. Nobody makes it to heaven by making sure that they followed each of these tradition of their ancestors. In His teaching to the crowd, Jesus added that there is nothing outside of a person, that if he does it, he is defiled. It is the things that come out that defile.
All human actions have their origin in the heart.
All these evil things come from within, and they defile a person. Called to be doers of the Word of God, we are not called to be doers of the worldly pleasures that rob the grace of God from our souls. There is no law against such things. Those who belong to Christ Jesus have crucified the flesh with its passions and desires. You must neither add anything to what I command you nor take away anything from it, but keep the commandments of the Lord your God with which I am charging you.
