The Zohar teaches us about the importance of putting on Tefillin (Phylacteries) every day. The head Tefillin has four chambers corresponds to the four chambers of the brain and the four letter of the YHVH name. The four are for Chokmah, Binah, right of Da’at that is the aspect of Tiferet (central column) and Left of Da’at (Malchut). These chambers spread the Light to the entire body.
“וְרָאוּ כָּל-עַמֵּי הָאָרֶץ, כִּי שֵׁם יְהוָה נִקְרָא עָלֶיךָ; וְיָרְאוּ, מִמֶּךָּ”
“So all the peoples of the earth will see that the YHVH name is called on you, and they will be afraid of you.”
When a man puts the Tefillin on his head and prays the YHVH name is ‘resting’ on his head and shines throughout the day or until that person does negative actions and disconnects himself from the holy name.
There’s a system that was developed to show the surrounding Light/Aura of a person. The inventor did extensive research to find the effect of different spiritual tools on the Aura of the people. When a person, any person, even a non-religious person puts a Tefillin on his head, his Aura changes/elevates. It’s the same with the Tallit, prayer shawl, that must have a Tzitzits on four corners. Similar shawl without Tzitzits have no impact. The experiment included reading of sacred text that also showed increased light around the person.
It is already known that the place of the Tefillin on head and hand is significant to the flow of energies in the body.
All of our spiritual tools, blessings, scanning, reading and studying Zohar, and every positive action is significant in adding Light of protection around us.
People that participated in this study started praying and wearing Tefillin every day after they saw the positive impact when using the spiritual tools.
Every Jewish men should wear Tefillin. Non-Jews in a process of conversion should consult with their rabbi to determine if and when they can start wearing Tefillin.
Here’s a link to the video about the study (in Hebrew).
