Asoka is defined as “Spiritual” and “Organized”
“Spiritual” means you have “No anarchy” during revolution. This means that you should change your civics and/or religion frequently (there is a general limit of 1 revolution in 5 turns however). Of course, when doing so you must take into account the effects of the chosen Civics and Religion. Temples are constructed at double speed, meaning that you should discover Priesthood and maybe think of founding several religions (discovering Polytheism is beneficial as it gives you both the Hinduism Religion and the path to Monotheism technology (with Masonry), which is required to Judaism). You should consider building missioners to spread religions, as it will lead to more happy people when switching to “free religion” civic in modern times.
“Organized” means you have to pay less for your civics – making the usually expansive Police State, Vassalage, Environmentalism and Organized Religion less painful. It also enables you to construct the “Courthouse” and “Lighthouse” at double speed, making the discovery of Sailing and Code of Laws logical. The latter is generally more important as the first to discover founds “Confucianism” religion. Courthouses will also lead you to the Forbidden Palace – reducing the corruption in your empire.
