012 – Elul 12 – Igeres Hakodesh, Chapter 13 – י"ב אלול – אגרת הקודש פרק י"ג

From Tanya - regular year - Rabbi Chaim Wolosow by R Chaim Wolosow.

This letter explains that among those who serve Hashem there are two distinct paths — one of restraint and measure, and one of expansiveness and open-handed generosity. Each stems from a different root among the Divine attributes, and it shapes how a person performs mitzvos: within careful limits, or without bound.
