Śānkarasmṛti (Laghudharmaprakrāśikā) is treatise in Sanskrit dealing with the customs and traditions of the people of medieval Kerala. The work calls itself "Laghudharmaprakrāśikā" and the term "Śānkarasmṛti" is not mentioned anywhere in the work. However at the end of every chapter there is a colophon which begins with the words "sāṅkare dharmaśāstre" which probably gave rise to the tradition of referring to the work as "Śānkarasmṛti". 
The work is originally supposed to contain thirty-six chapters, but only the first twelve chapters have been unearthed. Thus in that sense, the currently available manuscripts of the work are incomplete. The work is about the traditions and customs of Kerala at the time the work was composed. Many of these customs called "Keraḷācāra"-s are peculiar to Kerala and are not seen among people in other parts of India. At several places in the text, the author of "Śānkarasmṛti" invokes a certain work titled "Bhārgavasmṛiti" as the authority for his pronouncements. But unfortunately the work "Bhārgavasmṛiti" has not so far seen the light of the day, and moreover, in the whole corpus Sanskrit literature, except in "Śānkarasmṛti", there is no mention of a work titled "Bhārgavasmṛiti". It is believed that "Bhārgavasmṛiti" must have been a fictitious invention of the author of "Śānkarasmṛti".a 
Authorship.
Traditional scholarship assigns the authorship of "Śānkarasmṛti" to Adi Shankaracharya, the great philosopher and the most renowned exponent of Advaita Vedanta, who hailed from Kerala. The source of this attribution is a statement in the opening stanza of the text which reads "śāṅkareṇa yatātmanā" (meaning "Śaṅkara of ascetic disposition"). T. C. Parameswaran Mussatu (who published "Śānkarasmṛti" with a Malayalam commentary in 1926), Kodungallur Kuññikuṭṭan Tampurān and Kanippayyur Shankaran Namboodiripad are a few of the prominent traditionalists. The modern view which rejected the traditional view was strongly articulated by Ulloor S. Parameswara Iyer, the author of a multi-volume work on the history of Kerala literature. Ulloor S. Parameswara Iyer gave a host of reasons why Adi Shankaracharya could not be the author of "Śānkarasmṛti". These include the fact that Adi Shankaracharya's disciples has not mentioned this work in any of their writings, an ascetic of the stature of Adi Shankaracharya is unlikely to dwell upon such mundane matters and the use of the anachronistic term "janmi" to denote a landlord. Ulloor S. Parameswara Iyer suggests that the author of "Śānkarasmṛti" should be one Payyūr Śānkaran Nampūtiri who flourished during the 14th century CE. Vaṭakkuṃkūr Rājarājavarma Rāja, K. Kujunni Raja, P. Govinda Pillai, R. Narayana Panikker and S. Venkita Subramnia Iyer are some other scholars who have rejected the traditional view. The modern consensus view can be summarized thus: The author of "Śānkarasmṛti" is one Śānkaran Nampūtiri hailing from north Kerala who flourished during the 14th-15th century CE.

These include duties such as ""Kṣatriya"-s and "Vaiśya"-s should get up and show obeisance by standing and saluting when a "Brahmin" approaches, even if the latter is a young boy" and ""Śūdra"-s generally do not prostrate before of others, but they only stand aside in obeisance with folded hands, as ordained by the rules of "Bhārgava"".b. The book concludes with a list of sixty-four injunctions (called "anācāra"-s, meaning "deviations from accepted customs and practices") that should be followed by the people of Kerala. This list of "anācāra"-s begins with the instruction "One should not cleanse the teeth with sticks" and ends with "She should not die along with her husband (as in "sati")".c
