There is a concept in Judaism called Hiddur Mitzvah or beautifying the Mitzvah (commandment). This is generally an optional level of fulfilling the your religious obligations. This level of observance is for those that want to go above and perform the commandments at a higher standard, in a glorious manner.
Some examples are:
- A Torah Scroll written with fine inks, fine quill and wrapped in fine silk
- Buying special foods for Shabbos Kodesh (holy) to beautify the day and make it special
- Spending extra money to buy an extra beautiful flawless Ethrog (Citron)
- Buying a beautiful Lulav (Palm Frond)
- Building a beautiful Sukkah (Booth)
- Using an expensive Menorah (Candelabra) for Chanukah (Festival of Lights)
- When spending on a Mitzvah, add 1/3 to the amount you were originally going to spend
But the best example of a Hiddur Mitzvah is spending, after construction, over 1 million dollars for a building to be a Shul that is only used for "3%" of the week.
