Smiritis
Next in importance to the Sruti are the Smritis or secondary scriptures.
These are the ancient sacred law-codes of the Hindus dealing with the Sanatana-Varnasrama-Dharma.
They supplement and explain the ritualistic injunctions called Vidhis in the Vedas. The Smriti or Dharma Sastra is founded on the Sruti. The Smritis are based on the teachings of the Vedas. The Smriti stands next in authority to the Sruti (Vedas). It explains and develops Dharma. It lays down the laws which regulate Hindu national, social, family and individual obligations.
The works that are expressly called Smritis are the law books, Dharma Sastras. Smriti, in a broader sense, covers all Hindu Sastras (scriptures) save the Vedas.
The laws for regulating Hindu society from time to time are codified in the Smritis. The Smritis have laid down definite rules and laws to guide the individuals and communities in their daily conduct and to regulate their manners and customs. The Smritis have given detailed instructions, according to the conditions of the time, to all classes of men regarding their duties in life.
The Hindu learns how he has to spend his whole life from these Smritis. The duties of Varnasramas (the four stages of life) are clearly given in these books. The Smritis describe certain acts and prohibit some others for a Hindu, according to his birth and stage of life. The object of the Smritis is to purify the heart of man and take him gradually to the supreme abode of immortality and make him perfect and free.
These Smritis have varied from time to time. The injunctions and prohibitions of the Smritis are related to the particular social surroundings. As these surroundings and essential conditions of the Hindu society changed from time to time, new Smritis had to be compiled by the sages of different ages and different parts of India.
The Celebrated Hindu Law-Givers
From time to time, a great lawgiver would take his birth. He would codify the existing laws and remove those that had become obsolete. He would make some alterations, adaptations, readjustments, additions and subtractions, to suit the needs of the time and see that the way of living of the people would be in accordance with the teachings of the Veda. Of such law-givers, Manu, Yajnavalkya and Parasara are the most celebrated persons. Hindu society is founded on, and governed by, the laws made by these three great sages. The Smritis are named after them. We have Manu Smriti or Manava Dharma-Sastra (Laws of Manu or the Institutes of Manu), Yajnavalkya Smriti and Parsara Smriti. Manu is the greatest law-giver of the race. He is the oldest lawgiver as well. The Yajnavalkya Smriti follows the same general lines as the Manu Smriti and is next in importance to it. Manu Smriti and Yajnavalkya Smriti are universally accepted at the present time as authoritative works all over India. Yajnavalkya Smriti is chiefly consulted in all matters of Hindu Law. Even the present-day Government of India is applying some of these laws.
There are eighteen main Smritis or Dharma Sastras. The most important are those of Manu, Yajnavalkya and Parasara. The other fifteen are those of Vishnu, Daksha, Samvarta, Vyasa, Harita, Satatapa, Vasishtha, Yama, Apastamba, Gautama, Devala, Sankha-Likhita, Usana, Atri and Saunaka.
The Laws of Manu are intended for the Satya Yuga; those of Yajnavalkya are for the Treta Yuga; those of Sankha and Likhita are for the Dvapara Yuga; and those of Parasara are for the Kali Yuga.
The laws and rules which are based entirely upon our social positions, time and clime, must change with the changes in society and changing conditions of time and clime. Then only the progress of the Hindu society can be ensured.
