During Shabbat, we each receive an extra soul, or extra spiritual sensitivity. So, as Shabbat goes away, so does the extra soul, causing us to feel faint. For this reason we smell some spices to comfort our soul at the loss of Shabbat.
Cloves are generally used, but any pleasant-smelling spice or plant will do. Many households have a specially designed spice box to hold the Havdalah spices. Here are some of my favorites.
Beaded spice box on Etsy
Havdalah at Home on Etsy
Besamim Spice Box
Pomegranate design spice box
Echinacea Havdalah Spice Box
Make your own spice box from an empty tin like this one.Individual spice bags are perfect for a party.
In our own home, we use this stainless container I found at Whole Foods. I love the simplicity and sleekness and because it's air tight the spices stay fresh for a long time.
Have a great weekend and Shabbat Shalom!
