Chanakya remarks - "Dharma" & "Kama" both depend on "Artha"
It is true. The Daksha Smriti quite clearly validates the truth of Chanakya's statement in just a couple of verses.
No article is procurable without trouble. How can any religious rite be performed in the absence of [proper] articles ? There is no religion in the absence of rites.. And where is happiness in the absence of religion ? (22)
All persons seek happiness ; but that originates from religion. Therefore religion should always be carefully practised by all the castes. (23)
Daksha Smriti Chapter 3, Verses 22,23
The points made here are -- All persons love happiness (or fulfillment of desires i.e. Kama) and that follows from following religion (Dharma). Now, Dharma can not be followed without performance of rites (mentioned in Verse 22). Rites again isare not possible to be performed without all the necessary articles. And, lastly, to buy these articles one needs money (Artha) in the first place.
That's why Chanakya rightly points out that both Dharma and Kama depend on Artha.
