A person born under the influence of Mars known as the warrior planet, represents aggression, high energy, desire, and intensity as per Hindu astrology is said to have "mangala dosha" or "Kuja Dosha" ; such a person is called a Mangalika. According to the superstition, People with this dosha often show heightened anger, passion, or impatience—traits that may lead to tension in relationships, especially after marriage and the marriage between a Manglik and a non-Manglik is disastrous.
People who believe in this superstition think that a Manglik person will cause their non-manglik spouse's early death. To prevent this Mangal Dosha relief, obstacle removal the person may be married to a tree, an animal, or an inanimate object for marital harmony. This mock marriage custom has different names depending on the "spouse" used in the ceremony; for example, if the person is married to a clay pot, the ceremony is called "kumbh-vivah".

According to one belief, if two mangliks marry each other, they cancel out each other's bad effects.
