Answer: The Gematria (numerical value) named Nachshon ben Amminadab indicates the height of his spiritual condition is a property of a clean Bina.
It gives him the opportunity to stand up against a wall of water. On one hand, water is this soft property, which is the basis of life, and on the other hand, it is a harsh property as manifested as Gevurot, the force of the court.
The harsh and soft forces, lurking in the water, can be moved only by rising above egoism. Nachshon is able to do this because before a man breaks away from egoism, everything parts as he completely adheres to the Creator.
There is no empty space in the world: either reception, egoism, or bestowal, the property of the Creator. Once raised above the ego, you do not enter a vacuum but the property of the Creator, as Noah did when he entered the ark. So it is here, you enter the property of bestowal, as one may enter a cocoon, and there you exist in it. This is the effect of Nachshon. The sea harms someone, as in the story of the flood, and someone else gets to be saved.
Thus the actions of Noah and Nachshon are the same actions that occur at different levels of egoism and return to square one in the four stages of development. This takes place at each stage. This is the spiritual advancement.
