Thereafter came a flowering of the Shastraic literature on Artha and other aims of human beings: of dharma in Dharmashastras, of artha in Arthashastras, of kama in Kamashastras (Kamasutra being one part of the compendium). Different schools of Hinduism offer different perspectives on artha, just like dharma, karma and moksha. Most historical literature of ancient India from about 5th century BC and after, interlaces all four aims of humans. Many Upanishads as well as the two Indian Epics – the Ramayana and the Mahabharata – discuss and use the words dharma, artha, kama and moksha as part of their respective themes. Even subhasitas, gnomic and didactic Indian literature from 1st and 2nd millennium CE, incorporate artha and other three aims of human life.
