Machine Matzah and Why was the Mishna Brurah silent?

«One last question remains.  Why was the Mishna Brurah silent?  This author would like to suggest that at the time the Mishna Brurah was written, the other underlying issues were still a factor and had not been adequately resolved.  We can conjecture that as far as the Lishma factor, it seems likely that the Mishna Brurah would have voiced his opposition to the Matzos if he held that the Lishnma issue was truly unbridgeable.  He didn't permit it at the time because it was still loaded with problems and had he voiced his view would have been used to permit all sorts of problematic Matzos.  The wiser choice would have been silence – which the Chofetz Chaim did choose.  The Chofetz Chaim was one of the wisest of the generation and Chazal do tell us in Pirkei Avos – s'yag l'chochmah shetika – a good boundary for wisdom is silence.
This then may be the lesson of the Matzoh issue for Pesach.  Matzoh is called by the Zohar as "Bread of Emunah."  Emunah means belief and closeness to Hashem.  Pesach is the time where we draw ever closer to Hashem and this bond will hopefully continue with us throughout the year.»
