Bein Adam Lamakom - Rebbi Meir who certainly conquered his inner Yetzer Hara was attacked by an exterior form of the Yetzer Hara and almost succumbed to a prostitute, until Hashem called to the Yetzer Hara to leave him alone. While we have gone through the week step by step conquering our Yetzer Hara (Netzach) we still need the protection of Hashem. On the last day of Netzach, we daven (Malchus) to Hashem to help us achieve everlasting dominance over our Yetzer Hara.
Bein Adam Lachaveiro - Daven and light candles (Malchus) for those who have passed on to the eternal world (Netzach).
