קודם נעילה ביוה"כ יאמר מחזור בקטנות כדי שיוכל אח"כ להתפלל בדביקות:
Before Ne’ilah (The concluding prayer of Yom Kippur- the Day of Atonement) reserve your strength and recite the Machzor⁵⁹liturgy in a diminished state of Godly awareness-Katnut.⁶⁰ In this way, when you come to Ne’ilah, you will have the strength to recite it with great adhesion-Dveikut to HaShem.
footnotes: ⁵⁹ The Yom Kippur ⁶⁰ See chapters 34 & 35 of Shaar HaYichud of Rabbi DovBer of Lubavitch, translated with commentary as The Gate of Unity, as well as the different levels described in Kuntres HaHitpaalut translated as Divine Inspiration.
