The righteous people who are connected to Yessod of Zeir Anpin become part of ‘צרור החיים’, literally means ‘The Bundle of Living’ but it’s deeper meaning is to be part of the souls that will be resurrected and enjoy immortality. They would be on a level higher level than all the angels. Their place in heaven would be in the highest level of the Garden of Eden.
The Zohar later explains that the difference between the lower and higher garden of Eden is as the difference between light and darkness. This level is described in Isaiah 64:3
“וּמֵעוֹלָם לֹא-שָׁמְעוּ, לֹא הֶאֱזִינוּ; עַיִן לֹא-רָאָתָה, אֱלֹהִים זוּלָתְךָ–יַעֲשֶׂה, לִמְחַכֵּה-לוֹ”
“For from days of old they have not heard or perceived by ear, Nor has the eye seen a God besides You, Who acts in behalf of the one who waits for Him.”
The root of this term “bundle of living” comes from 1 Samuel 25:29 (read the entire chapter for the interesting story related to King David)
“וַיָּקָם אָדָם לִרְדָפְךָ וּלְבַקֵּשׁ אֶת נַפְשֶׁךָ וְהָיְתָה נֶפֶשׁ אֲדֹנִי צְרוּרָה בִּצְרוֹר הַחַיִּים אֵת יְהוָה אֱלֹהֶיךָ וְאֵת נֶפֶשׁ אֹיְבֶיךָ יְקַלְּעֶנָּה בְּתוֹךְ כַּף הַקָּלַע”
“Should anyone rise up to pursue you and to seek your life, then the life of my lord shall be bound in the bundle of the living with YHVH your God; but the lives of your enemies He will sling out as from the hollow of a sling.”
The “Bundle of Living” is for the righteous and the “hollow of sling” is for the most evil. Their souls are casted between worlds in a very painful restless process for a very long time. (See also Zohar Beshalach #321-325)
On almost every Jewish tomb stone we find the letters ת.נ.צ.ב.ה. They are initials for “May his soul be bundled in the bundle of the living”. This is the best wish we can make for those who passed away.
