Daya Krishna argues that "artha", as well as the concept of Puruṣārthas, is a myth. The various schools and ancient Sanskrit texts provide no consensus opinion, notes Krishna, rather they present a debate, a diversity of views on what "artha" and Puruṣārtha means. Inconsistencies and conflicting verses are even present within the same script, such as the Manusmriti. Some ancient Indian texts suggest artha are instruments that enable satisfaction of desires; some include wealth, some include power, and some such as the bhakti schools include instruments to love God. Some of this, suggests Krishna, reflects differences in human needs. Perhaps, conjectures Krishna, artha is just a subset of kama and karma.
