Hi, My name is Sam, and I am demonstrating my knowledge of the Bar/bat mitzvah. First, life changes once you reach the Bar/bat mitzvah. Girls do it when they are 12 because they typically develop faster than males, who do it at 13. When done with our Bar/bat mitzvah, you can participate in the Minyon and Alliyah.
The purpose it serves is that when you do the ceremony and finish reading your Torah portion, you are an adult in Jewish eyes and are now able to participate in fasting and other things. It is also very important like the summary of what G-d said about that G-d saved us and stuff.
I found the sea snail (Chilazon) mystery interesting because over a really long time ago, scientists said that it appeared every 70 years, but now they just appear. I also find it interesting that the Teffilin doesn’t cut off your arm circulation because it looks tight in pictures and videos demonstrating how to wear it. Also, I find it interesting because of the math of the 613 mitzvahs that someone had to do.
I still have many questions about what the sea snail looks like, why they stopped wearing the tallit gadol daily only after the destruction of the second temple, why they now wear it as a prayer shawl on morning prayers and other important days, and how they constructed most of the stuff.
