In the last two years one can hardly try to plan something for the near future. I thank all in person and online participants in the Symmetry Festival 2021, which was held in Sofia. We are looking forward to the next Symmetry Meeting, which will be probably held in Pécs, Hungary, in 2023 after the official approval by the ISA Board. I hope most of us shall be able to attend in person by then. The next year is declared by UNESCO as an International Year of Basic Sciences for Sustainable Development (https://www.iybssd2022.org/en/home/) with a lot of scientific and technical partners and supporters. Symmetry is a universal principle, as well as a way of thinking and a way of life! It has no borders for sciences, arts and innovations!
I take the chance to wish you all a healthy and prosperous Happy New 2022 Year!

The Rila Monastery is the largest and most famous Eastern Orthodox monastery in Bulgaria. It was founded in the 10th century by the heavenly protector of the Bulgarians Saint John of Rila after the official adoption of the Christian religion in Bulgaria in 865. During the centuries the monastery was destroyed and abandoned several times. The monastery and its church were rebuilt in the beginning of the 19th century. It became a center of spiritual and cultural life during the Bulgarian National Revival Period. The Hrelyu’s tower is the oldest preserved monument dating from 1335. The main church is decorated with mural paintings and exquisite wood carvings by the best representative of the Samokov, Debar and Bansko-Razlog schools. Since 1983 the Rila Monastery is listed as UNESCO World Heritage Site.
