What Is the purpose of changing seats on getting married?
When Then a man and woman get married, the first thing they do is change seats so that the wife sits on the left of the husband.
According to the Mahabharata, Shanti Parv, 235118, a wife is part of the husband's body. For this reason she is often referred to as the better half. This also symbolizes that only after marriage a man becomes a complete person.
In the Taittriya Brahman, 33/3/5, it is said:
A man's body is not complete until a woman fills it to make it whole.
According to Hindu religious texts, Brahma created man from the right shoulder and woman from his left shoulder. A woman is referred to as Vamangi; or one who is on the left side. Throughout the marriage ceremony the bride sits on the right side of the groom. That is the place for strangers and acquaintances. Only after the saptpadi, when the bride and groom have exchanged marital vows, is the wife seated on the left side of the man. The left side is considered close and intimate. After marriage the wife becomes the prime manager of the household, and with transfer of responsibilities she also changes place from the right to the left. Hindus refer to this as 'change of seats'.
