Iggeret HaKodesh, middle of Epistle 27
והנה, בהיות הצדיק חי על פני האדמה, היו שלש מדות אלו בתוך כלי ולבוש שלהם
Now, while the tzaddik was alive on earth, these three attributes were contained in their vessel and garment
בבחינת מקום גשמי, שהיא בחינת נפש הקשורה בגופו
on the plane of physical space, this being the aspect of the Nefesh which is bound to his body.
וכל תלמידיו אינם מקבלים רק הארת מדות אלו, וזיון
During his lifetime his disciples all receive only a reflection of these attributes, and a ray from them
המאיר חוץ לכלי זה, על ידי דבוריו ומחשבותיו הקדושים
that radiates beyond this vessel (i.e., the tzaddik’s body) by means of his holy utterances and thoughts.
