Smriti
Smriti(s) are the books of social, economic and political laws which are changeable with time and have been composed by scholars from time to time as the need was. Amongts 250 Smrities (known to have been mentioned in different texts) only some 57 are traceable now, the most prominent ones being Manu Smriti.
