FWIW, 'time' isn't circular in Hinduism either, at least not in the way the article makes it out to be. The physical universe has a cycle of creation & destruction, but each cycle is distinct from the other. The general beats of each cycle are largely the same, but the souls move through them in linear fashion. An analogy might be made with a theatrical production: each night set pieces & backgrounds go through a fixed order, and the cast moves through the set according to the script, but the actors in the cast can change over time. In schools of thought such as Saiva Siddhanta, the manifest universe is created with the express objective of providing a platform for souls to move through and work out their issues before achieving enlightenment. Souls that achieve enlightenment don't return to the material world (with some caveats), with the universe resetting on a regular basis for the rest of the souls to have another go at it. Some schools of thought in Hinduism (Vashishta Advaita, Dwaita (?), Gaudiya) envision a multiverse that resets, but time still moves only in one direction.
