“בְּהִתְהַלֶּכְךָ תַּנְחֶה אֹתָךְ בְּשָׁכְבְּךָ תִּשְׁמֹר עָלֶיךָ וַהֲקִיצוֹתָ הִיא תְשִׂיחֶךָ”
“When you walk about, they will guide you; When you sleep, they will watch over you; And when you awake, they will talk to you.”
The Torah channels the life force of the Tree of Life.
‘When you walk’ – guide us in our daily work.
‘When you sleep’ – the soul ascends at night and the Torah protects the body below and the soul on its way up for the night rest and recharge, and on the way back down to the body.
‘When you wake up’ – the Torah waits for us to restore the life force in the body.
“כִּי נֵר מִצְוָה, וְתוֹרָה אוֹר; וְדֶרֶךְ חַיִּים, תּוֹכְחוֹת מוּסָר”
”For the precept is a candle and the Torah is light; And the way of life, a reproofs for discipline”
“עֵץ חַיִּים הִיא לַמַּחֲזִיקִים בָּהּ וְתֹמְכֶיהָ מְאֻשָּׁר”
“She (The Torah) is a tree of life to those who take hold of her, And happy are all who support her.”
There people who don’t have certainty and worry about their material existence. Rabbi Yehuda answers them quoting Psalms 37:3
“בְּטַח בַּיהוָה וַעֲשֵׂה טוֹב שְׁכָן אֶרֶץ וּרְעֵה אֱמוּנָה”
“Trust in YHVH and do good; Dwell in the land and cultivate faithfulness.”
If we trust YHVH with certainty, act with good consciousness then we can live in the material world, Malchut, without worries. A complete faith creates connection to Chokmah and Binah that provide everything we need in this world.
The Zohar adds that with such faith no one in the world can harm us.
