Hagigah
Tractate Ḥagigah (literally "Festival Offering") deals with the Three Pilgrimage Festivals (Passover, Shavuot, Sukkot) and the pilgrimage offering that men were supposed to bring in Jerusalem. At the middle of the second chapter, the Talmud discusses topics of ritual purity.
The tractate contain three chapters, spanning 27 pages in the Vilna edition, making it relatively short. The second chapter contains much aggadah, describing creation, and the Merkabah. Its content is relatively light, except for the third chapter.
