This is what Wikipedia has to say about Indian weddings-
Indian weddings are very bright events, filled with ritual and celebration that continue for several days. They are generally not small affairs, with anywhere between 100 to 10,000 people attending. Often times it is possible that many of the attendees are unknown to the bride and groom themselves. Though most Indian marriages are arranged, some couples in urban areas have what are known as “love marriages”, where the partners decide to marry each other without family involvement or assistance. The traditional Indian wedding is more about two families being brought together socially, with much less emphasis on the individuals involved.
The best thing about Indian weddings is that, no one exactly knows what rituals are to be taken place.
Picture this- four to five elderly ladies fighting over the sequence of the ritual. Where at the same time the groom or the bride to be is sitting half naked, covered in turmeric paste.
The ladies can be heard saying- “humare yahan to aisa hota hai” (in our tradition, the ritual takes place in this manner) or something like- “apshagun hoga” (if this happens, bad luck will follow).
The groom/ bride’s mother gets worried if someone points out, “you didn’t do ‘that’ work”. Now this ‘that’ can be anything ranging from any particular ritual or ceremony. Scared of bad luck, the groom’s mother does as the person says! The family takes all this pain to ensure the children stay happy and blessed in their married lives.
Alas! Today we are blindly following these traditions, without even understanding its relevance.
