Kumbh Vivah is a Hindu ritual where a person who has Manglik Dosh in their birth chart gets married to a Peepal tree, a Banana tree, or a silver or golden idol of Lord Vishnu before getting married to their actual partner. Manglik Dosh is believed to be an astrological condition that occurs when Mars is placed in the 1st, 4th, 7th, 8th, or 12th house of a person's birth chart. It is believed to cause marital discord, delays, and sometimes even death of the partner.

Kumbh Vivah is performed to neutralize the effects of Manglik Dosh. After performing the Kumbh Vivah, the person is believed to be free of Manglik Dosh and can marry their actual partner without any adverse effects. The Kumbh Vivah ceremony involves tying the knot with the tree or idol, followed by a puja or worship ceremony.

However, it is important to note that while Kumbh Vivah is a widely accepted practice in Hindu culture, its efficacy in resolving Manglik Dosh is not scientifically proven. It is always advisable to consult a qualified astrologer before taking any decision related to one's birth chart or marriage.
