Ayin and Yesh

Ayin and Yesh are two Hebrew letters. The letter Ayin is written like an O and looks like a little circle and it is the 17th letter of the Hebrew alphabet. The letter Yesh looks like a Y and it is the 15th letter of the Hebrew alphabet. Both letters have a special meaning. Ayin is the letter of 'nothingness' and Yesh is the letter of 'somethingness'. In other words, Ayin symbolizes the idea that something can be nothing and Yesh symbolizes that something can be something. This is why they are often used together in prayers and special religious ceremonies to help people understand that everything is always changing and nothing is set in stone.
