The Mauryan Empire united much of India, and under Asoka, a practical unifying ethos of Dhamma was formulated by combining elements of Buddhism and Hinduism that was "pragmatic and intensely ethical." A moral discipline was imposed by Asoka's Dhammic edicts, prohibiting excessive feasting and drinking, animal fights and sacrifices. Family was the social foundation. Theft was rare, laws were straightforward, resources and food were abundant, metallurgy, manufacturing textiles, and carpentry, including boat-building, were widespread and impressive, according to Greek observers. Typical of the High Culture cycle, economic activity was organized through guilds. Merchants were forbidden excessive profits and subjected to laws protecting the public from poor-quality goods. Mauryan India was noted for its excellence of its stone monuments and buildings, initiated by Asoka. In particular the Mauryan stone columns, crowned with colossal animal sculptures were considered without equal in the world.
