Hayom Yom: Iyar 8 23rd day of the omer

An emissary is one with his sender. This concept is similar to that of an angel acting as a Divine emissary, when he is actually called by G-d's name. If this is so with an angel it is certainly true1 of the soul; in fact with the soul the quality of this oneness is of a higher order, as explained elsewhere.2

Now chassidim are emissaries of the Rebbe, the Alter Rebbe. So if the chassid actively discharges his mission, he is bound up with his Rebbe, bound up in his entire being - there walks a chassid, there eats a chassid, there sleeps a chassid.
