One more thought (Uh Oh)
At the time of Yitzchak Avinu’s birth, Sara Imeinu said כל השומע יצחק לי, Rashi quotes Medrash that says ‘A lot of barren women were remembered with her, a lost of sick were healed that day, a lot of Tefillos were answered that day, therefore a lot of joy was in the world (at that time)’
The connection to me is obvious. Avraham Avinu and Sara Imeinu, being the Shleimim (wholesome) that they were, couldn’t relish in their own joy and happiness, while seeing neighbors and friends suffering. So INCLUDED with their Tefillos for their own Yeshua, was a Tefillah others. A true Shaleim cannot enjoy own blessings while his friend is lacking. Perhaps that is the essence of Purim, Matanos L’evyonim, Mishloach Manos, because for one to experience real joy, all his friends and neighbors must be happy too.
On Purim we get a bit selfish, we even give to others, just to make ourselves happy!
Let's try to hold on to that idea!
(Forgive me for .. it’s another outgrowth of my thought contraption)
