Shining Through

 וְהָיָה֩ לְךָ֨ לְא֜וֹת עַל־יָדְךָ֗ וּלְזִכָּרוֹן֙ בֵּ֣ין עֵינֶ֔יךָ לְמַ֗עַן תִּהְיֶ֛ה תּוֹרַ֥ת י״י֖ בְּפִ֑יךָ כִּ֚י בְּיָ֣ד חֲזָקָ֔ה הוֹצִֽאֲךָ֥ י״י֖ מִמִּצְרָֽיִם.  What does tefillin have to do with Torah?  And what does that have anything to do with yitziat mitzraim?  And why say the Torah is in your mouth?  Tefillin gives one the ability that the נשמה should be able to have dominion over the body.  But more than just being able to control the animal instincts of a person, tefillin allows for the soul to express itself.  How does a person express themselves?  Via talking.  The person's ability for the soul to shine forth is present in speech which is the meeting point of רוחני  and גשמי.  That is why it is tefillin that allows for Torah, the ruchni to be able to come to fruition בפיך, in the Torah שבעל פה, in the interaction between a person's own physical being and Torah.  This idea was expressed in yitziat mitzraim where the ruchni took control over the gashmi world and transformed it.  This is what it means that in mitzriam the דעת or דיבור was in golut and it became redeemed.  As slaves, one has no self expression, there is no תורה בפיך, there was no unique Torah of the individual.  Yitziat mitzraim allowed for that to happen.  The tefillin allows the neshama of a person to shine through (Sfas Emes 5635 and other years.)
