7 Tamuz - Shaar Hayichud Ve'HaEmunah - chapter 11

As we we know the world was created by 10 Maamarot .
When we talk about Maamarot - "sayings" of Hashem we are basically talking about vessels for the the light .
In the human soul there are movements - midot . What are these Midot? they are potentials. A person is born with a certain nature and that are his natural Midot.
The Midot are expressed by the persons actions. This why we see that a person who has a strong Mida of Chessed will busy with giving.
Rabbi Yeruslavsky , one of the famous Chassisdim of our time, is a good example for this.
R. Yerusalvasky has established a large Chessed "factory" around his home . At times he would feed hundreds of people. The interesting this was that when he came to New York , to the Rebbe , he could not sit still without feeding someone! He would eat his meals at a restaurant and would always have a few people eating with him . Even as a guest he had his own guests! The actions he took later became the famous Hachnasat Orchim of 770 that runs toady.
Well, we see that when a person has the an urge for Chessed he gets special strengths to fulfill his essence.
The same goes for Hashem . Hashem has an abstract will for Chessed or Gevurah and this will comes down to a vessel that is referred to as "Letters" (Otiyot) or "Words" (Tei'vot). That is why we say that the world(s) was created by Hashem's Maamarot (Sayings) . We are basically saying that the world(s) where created using containers reducing (Metzanatsem) Hashems light.

Another thing about the Chessed Midda -
the Midda of Chessed means Hitpashtut (Extending) and not Tov (goodness) like most people think.
The Mida of Tov is referred to the Yessod Seffira, the action of Yessod is (Hashpaa) influencing .

Personal thought of today : I should start getting my personal Chessed Mida in to action a little more!
