Netzach and Hod are called “the wings of Yesod,” in how they work to make connections and bring spirituality into the world. Aish haTorah calls this triad of Sefirot, “tactical,” meaning that their purpose is not inherent in themselves, but rather as a means for something else. Netzach, on the ‘proactive’ side, relates to endurance in reaching goals.
Two quotes from Rabbi Nachman of Breslov that relate to this aspect of Netzach:
“Each mitzvah that a person does in this world creates a lamp with which he can explore the treasure house of the King after he dies. This is the ultimate bliss of the life to come.”
– Likutey Moharan I, 27
“When a person rises from level to level in this world, never ceasing to make fresh advances in serving God, so too in the world to come he will continue rising from level to level.”
– Siach Sarfey Kodesh 1-85
Moshe’s sister, Miriam, represents Netzach through her endurance as a prophet, bearer and bringer of water (the right side) and tzedekes for the people.
