(1.) Adherence to Dharma - Religion is of utmost importance in the Sanatani Hindu society. The importance of yajna from the Vedic age and the cooperation of everyone was expected in it. Dev-worship and Yagya-Kriya has been the pillar of religion. All the sacraments have been influenced by Yagya, Havan and Dev Puja. Without them, the completion of the sacraments is considered incomplete. Therefore, marriage rites have also been performed on the instructions of religion. The first purpose of marriage is - the performance of religious functions, which a person can do only when the wife is alive. No religious work of a person is considered complete without a wife.

 Therefore, the presence of the wife was necessary in all religious functions. Yagyas are of utmost importance in religious activities. There are five types of Yagyas – Brahma Yagya, Dev Yagya, Bhoota Yagya, Pitru Yagya and Atithi Yagya. In performing these yagyas, it is said that it is necessary for a man to have his wife along with him. According to Rigveda, marriage makes a person a householder and gives the ability to perform sacrifices for the gods. Husband and wife are considered to be the helpers of each other in the worship of the gods. It is mentioned in the Taittiriya Brahmana that a person without a wife is not entitled to perform the Yagya.

In the Shatapatha Brahmana it is said that the wife is the complement of half of the husband. In such a situation, the combination of both of them is complete. Actually, the husband is complete only after getting the wife. It is accepted that both should cooperate with each other in all yagya activities. Seeing the necessity of the wife in the life of the husband, Yajnavalakya says that after the death of the wife, a second marriage should be done for religious purposes. The one who sits together in the Yagya is called 'Wife'. The person who performs a religious act by abandoning a virtuous co-religious wife, all his religion becomes fruitless. Dharma, Artha, Kama and the attainment of a son are achieved by the union of both husband and wife.

Apart from the pure religious functions, many religions of the householder also come under this, which are accomplished with the cooperation and enthusiasm of the wife. Therefore, marriage is the core of household life, in which a person follows the dharma by performing various deeds.

(2.) Procurement of a son - The second purpose of marriage is to have a son. The attainment of a son is considered to be a naturally strong aspiration of man. This desire for children is very ancient. It is said in Rigveda that Panigrahan is for the best children. After the completion of the marriage, the priest has been blessing the bride and groom to have many sons.

From the Vedic age to the present day, there has been a strong desire for children in man and he has also been expressing his excellent desire for him, because the son has immense importance in the Hindu society. With the birth of a son, the father is believed to have attained immortality and he is freed from the debt of the father and removes tamas from life. For the father, the son is Alok and the 'Atitarini' (boat) to cross the ocean of samsara. A sonless person has no place in the society and neither does he have any other best world. That is why the son is also called the creator of the second world. According to Manu, the father receives from the son the best worlds like heaven, etc.

In the Mahabharata also, a son with a son has been praised and a sonless person has been condemned. The meaning of the son lies in the fact that he prevents the father from going to hell (Kumbhipak) called 'Put'. Father's name, lineage, family and society run from son and father's prestige. By the birth of a son, the father receives the fruit of bathing ten Ashwamedhas, and the ancestors get tarpan and pind daan from their children after a while. The son completes the rites to be performed after death.

Summary - In short, it can be said that the Indian theologians, keeping in view the social development, expressed their views on the progeny and emphasized the necessity of having children. Gave. That is why he kept the birth of son under religious action and accepted its quality and greatness on social basis. The continuation of the family, the expansion of society, the arrival of new generations respectively and the practice of religious activities have been basically based on the generation of children.

(3.) Rati-sukh- Marriage also had a purpose of rati-sukh or the satisfaction of sexual desires, which the ancient settlers said to be necessary for man, because the satisfaction of sex maintains the mental and physical balance of the person and he maintains a healthy and virtuous basis. But it builds the society. Although 'Kama' or 'Sexual relationship' is definitely an object of marriage, but it has been given the third place. This shows that this is the less expected purpose of marriage.

To emphasize the continued role of sex in marriage, it is said that the marriage of a Shudra is only for sexual relations. The position of the Shudra was low, so the purpose of his marriage was considered to be only sexual relations. Certainly, marriage is a civilized and cultured medium for the fulfillment of sexual desires. In the Vedic age sexual intercourse is considered the culmination of pleasure. Even the arrangers like Manu have accepted the importance of Rati and have considered it as the prime in the purposes of marriage. Vatsyayana has discussed in detail the importance of Rati in his Kamasutra. 

Through his analysis of thoughts, he has inserted the subtle subtle expressions of work. The place of sex-spirit in the Hindu social system and philosophy has never been more important than religion.

Kautilya is of the opinion that the work which is not opposed to religion and artha should be served. Manu has also advised to give up work against religion. But in the society it is considered against religion to react with a woman other than the religious wife. In such a situation, in the purposes of marriage, pleasure or pleasure is not over all, but it is said to be secondary. The above-discussed objectives make a person very polite and virtuous and make him regular and controlling. 

According to the scriptures, if a person gets sexual freedom, then the society will become uncontrolled and irregular and his moral decline will happen. In such a situation, there will be an atmosphere of disorder and unrest everywhere. Therefore, the institution called marriage guides the individual to the society. The upliftment of the personalities of both men and women takes place on the basis of these objectives. 

From the combination of both, children are born, which appear to be of their love and affection. The holy and holy harmony of both paves the way for a well-ordered life and physical, intellectual and spiritual spirit develops in the life of both. The continuity of family and social ethos, tradition-practice and religion-karma makes the continuous flow of marriage and contributes to the building of a civilized society.
