However I think is important to re-approach how we look at the period 'Between the Straits' - the mourning and customs that surround this propitious time in Jewish History. For example, one of the common customs is not to eat meet during the 9 days of Av. This minhag is grounded in two principles:
- The loss of the Temple sacrifices - most of the sacrifices where of animals and to remind ourselves of the loss of this service (the tamid) we refrain from eating meat and even from wine (libation offerings).
- Meat = Joy - sorry vegans and vegetarians, but many rabbis associate meat eating with Joy; thus with the loss of the Beit HaMikdash, we show our mourning by not eating meat, drinking wine, and wearing new clothes.
