This Sugya focuses on defining Hiddur Mitzvah, literally translated to mean “beautifying a Mitzvah.”  The term "Hiddur Mitzvah" is most frequently used to refer to the beautification of items used in performing the Mitzvah; for example, purchasing a nice Tallis, using beautiful Daled Minim, honoring Shabbos and Yom Tov with elaborate Seudos, wearing beautiful clothing, and using silver goblets, etc. 

However, there is another element of Hiddur Mitzvah –  beautifying and enhancing the manner in which it is performed.   This is culled from the Gemara in Maseches Shabbos that describes how to perform a Bris Milah in the most Mehudar fashion.  (The Mitzvah of Bris Milah is found in the Parshas – Lech Lecha.)

Some examples of this type of Hiddur:

• 
  Limiting eating on Erev Pesach to have an appetite for the Mitzvah of Achilas Matzah.
• 
  Tying the lulav together with the Aravos and Hadassim into a single bundle.  
• 
  A more Mehudar Esrog (according to all Halachic opinions) vs a more aesthetically beautiful Esrog.
• 
  
• Beautifying a mitzvah when no one will actually see the beauty (for example, Mehudar Parshiyos of Tefillin) 
• 
  
• And much more
