ויאמר הוי’ אל משה… בעשור לחודש… ויקחו להם איש שה לבית… ה’תשמ”א.

This Ma’amar discusses the idea of one being a seminal point which matures when it develops all ten aspects. It interprets the word בעשור (as opposed to בעשירי) as meaning all ten, meaning, that each later day includes all the preceding ones until ten. Ten is the completion of one’s personal wholeness; of קשוט עצמך. After the ten are complete begins the process of קשוט אחרים. This explains why on the eleventh of Nissan they took a sheep for a Korban and counted off four days. This is also connected to 10 Shvat as being the completion of what starts (in Shvat) on Rosh Chodesh.
