Lakshmi, along with Parvati and Saraswati, is a subject of extensive Subhashita, gnomic and didactic literature of India. Composed in the 1st millennium BC through the 16th century AD, they are short poems, proverbs, couplets, or aphorisms in Sanskrit written in a precise meter. They sometimes take the form of dialogue between Lakshmi and Vishnu or highlight the spiritual message in Vedas and ethical maxims from Hindu Epics through Lakshmi. An Example Subhashita is Puranartha Samgraha, compiled by Vekataraya in South India, where Lakshmi and Vishnu discuss niti(right, moral conduct) and rajaniti(statesmanship, right governance) - covering in 30 chapters and ethical and moral questions about personal, social and political life.
