When one person is Manglik in a marriage, the negative effects of Mangal dosha can be cancelled by performing this ritual called Kumbh Vivah. According to Hindu Vedic Astrology a Manglik person is made to marry a Banana tree, peepal tree, or a silver/golden idol of Lord Vishnu.

Is there any remedy for Manglik Dosha?

Recite Mangal Chandika sloka everyday sitting before the idol of Ma Durga. Perform ceremonies like Kumbh Vivah (marriage with a sacred pot), Vishnu Vivah (marriage with Lord Vishnu) or Ashwatha Vivah (Marriage with papal tree). Do bird feeding regularly. Every day make it a routine practice to chant Hanuman Chalisa.
