Rabbi Shimon says that when a person rises after midnight to study Torah until the morning light and then put Tefillin on his head and on the holy mark that is the Tefillin on the arm. Then wrap himself with a Tallit and about to leave his home, he sees the Mezuzah that is a holy mark in Malchut on the doorpost of his home.
Then four holy angels accompany him and escort him to the synagogue and announce ahead of him “give honor to the son of the King that has the image of his king”. A holy spirit on him announce and say “In Whom I will show My glory”.
“וַיֹּאמֶר לִי עַבְדִּי אָתָּה יִשְׂרָאֵל אֲשֶׁר בְּךָ אֶתְפָּאָר.”
“He said to Me, “You are My Servant, Israel, In Whom I will show My glory.”
The holy spirit ascends up to testify on that person in front of the Holy King. Then the King orders to write in the book of remembrance all of those who are honored to come into his palace.
“אָז נִדְבְּרוּ יִרְאֵי יְהוָה, אִישׁ אֶל-רֵעֵהוּ; וַיַּקְשֵׁב יְהוָה, וַיִּשְׁמָע, וַיִּכָּתֵב סֵפֶר זִכָּרוֹן לְפָנָיו לְיִרְאֵי יְהוָה, וּלְחֹשְׁבֵי שְׁמוֹ”
“Then those who feared YHVH spoke with one another. YHVH paid attention and heard them, and a book of remembrance was written before him of those who feared YHVH and thought upon his name.”
The Zohar explains that ‘and who thought upon his name’ has the meaning like in Exodus 35:32
“וְלַחְשֹׁב, מַחֲשָׁבֹת–לַעֲשֹׂת בַּזָּהָב וּבַכֶּסֶף, וּבַנְּחֹשֶׁת”
“to design (וְלַחְשֹׁב) artistic works in gold, silver, and bronze”
The root word is ‘חשב’ that is ‘thought’ and the verse above described Betzalel’s skills to build the HolyTabernacle with his thoughts to manifest the materials that are used in the Holy services.
In addition to those who fear and awe of God, the Zohar add those that honor his name by using the best Tefillin. the writing of the scrolls inside, the housing and straps. Also the strings of the Tzitzit, the blue string, and the Mezuzah.
The tools we use for spiritual connection are very important to establish a proper unification of Light and vessel. Our Tefillin should be of the highest quality we can afford, made by a scribe known to be righteous and does his work with proper consciousness (thoughts). Even Though we can achieve great quality in writing and forming the Tefillin leather houses in a perfect way, we do not use machinery or robots to produce our spiritual tools because machines of any kind can not add the proper consciousness that should be attached to that tool. The Tefillin should be checked at least every three years if they are of high quality. The ink may fade due to changes in environmental temperature and the letters may get broken during a spiritual ‘fight’ while protecting the wearer from external negative forces.
If a tefillin examination finds such issues then the person should look into his actions and correct himself.
The Tzitzit should be tight by a person with proper meditation. There are stores that sell cheap Tzitzit with the strings tied by machine. Not recommended.
