Pesach complaints and chumros
The source of Pesach Chumros:
The Rishonim and Poskim record that the Jewish people are holy and go above and beyond the letter of the law requirements on Pesach. The Arizal states that on Pesach one should be stringent to follow all the stringencies.
Justifying Pesach complaints:
One may not say “How troublesome is Pesach”, as this is similar to the statement of the wicked son. Nevertheless, today people are not careful in the above and some Poskim have learned merit to justify these statements. They learn that one is only similar to a Rasha when one complains regarding the Mitzvos of Karban Pesach, and other Mitzvos which are Biblical, as by saying this one makes it seem that the commands of the Torah are a burden on him. However, today this statement is said in reference to all the great stringencies which are accustomed with Pesach, and when he says on them how troublesome they are there is no prohibition in the matter.
Reason for Pesach Chumros:
First Mitzvah we accepted: The Mitzvah of prohibiting Chametz was the first Mitzvah given to all the Jewish people, and they therefore accepted it with love and affection, and were stringent in it regarding all details.
Chametz symbolizes the Yetzer Hara: The reason that the Torah was so stringent regarding Chametz is because Chametz symbolizes the Yetzer Hara, as just as Chametz is defined as bread that has risen, so too, the Yetzer Hara derives from haughtiness. Therefore, the Torah gave very strict rules regarding the Chametz on Pesach, in order to banish the Yetzer Hara completely from within us.
Banishes the Yetzer Hara to the point one does not sin: The Arizal states that on Pesach one should be stringent to follow all the stringencies, as one who is careful to avoid even a speck of Chametz on Pesach is guaranteed not to sin throughout the year. [This means that his nature will change to the point that it is so refined that he will not naturally do a sin inadvertently. However, regarding sinning advertently, one always retains his freedom of choice.]
Idolatry: Chametz is referred to by the Zohar as idolatry.
Ideally, according to Halacha, one is not allowed to be stringent regarding Rabbinical matters more than the stringencies of the Shulchan Aruch, nevertheless, regarding Pesach, the Jewish people are holy and go above and beyond the letter of the law. Nonetheless, this only applies if the custom has some basis or source, one however is not to innovate new Chumros that have no base in Halacha.
Being Machmir not to offend others with your Chumros:
It once occurred by a Pesach meal on the table of the Rebbe Rayatz in New York that a certain uneducated guest dipped his Matzah in the Borscht [beet soup], performing a grave sin in the eyes of the Chassidic brotherhood that were present by the meal. As can be understood, a great tumult transpired surrounding the actions of this guest, and the other Chassidim present gave the guest a piece of their mind. The Rebbe Rayatz inquired as to the reason behind the commotion and was told of the grave actions performed by the guest on his very own Pesach table. The Rebbe Rayatz nonchalantly replied “It is better that the Matzah become red [with the Borscht soup] than you cause the face of a Jew to redden in shame.”
