"Arak or Kumbh Vivaah" is a Hindu custom that involves marrying a person to a tree or an inanimate object, such as a pot (kumbh), in order to neutralize certain astrological doshas (afflictions) in their horoscope. This practice is typically performed when an individual is believed to have a dosha that may affect their future spouse negatively. By marrying a tree or a pot symbolically, the dosha is transferred to the object, thereby nullifying its harmful effects on the individual's actual marriage.

The rationale behind Arak or Kumbh Vivaah lies in the belief that certain astrological combinations, such as Mangal Dosha or other doshas related to specific planets, can lead to marital discord, health issues, or other challenges for the spouse. Marrying a tree or a pot is considered a way to appease these planetary influences and ensure a harmonious and prosperous marriage for the individual in the future.

It's important to note that while this practice has traditional roots and is still observed in some regions, its efficacy and relevance may vary based on cultural beliefs and individual interpretations of astrology. Additionally, modern approaches to astrology may offer alternative remedies or solutions to address doshas, and individuals may choose to explore these options as well.
