3934 – Wherever You Are, Your Purpose Is to Bring Torah, Mitzvos, and Chasidus – בכל מקום שאתה נמצא, מטרתך היא להביא תורה, מצוות וחסידות

The Rebbe writes that wherever a person finds themselves, it is by Divine providence for the purpose of illuminating that place with Torah, mitzvos, and Chasidus. Even after leaving, one should maintain ties to strengthen inspiration. G-d grants the strength to fulfill this mission. https://www.torahrecordings.com/rebbe/igroskodesh/012/003/3934
