Manglik dosha puja is a Hindu ritual that is performed to remove the negative effects of the Manglik dosha. According to Hindu astrology, a person is said to have Manglik dosha if Mars is placed in the 1st, 2nd, 4th, 7th, 8th, or 12th house of their birth chart. Manglik dosha is believed to cause various problems in a person's life, such as delayed marriage, conflicts in married life, and health issues. To mitigate the negative effects of Manglik dosha, a puja or ceremony is performed by a qualified Hindu priest. The puja involves the recitation of Vedic mantras and the offering of various items such as flowers, fruits, and sweets to the deity. The person for whom the puja is being performed is also required to make certain offerings and perform certain rituals. It is important to note that Manglik dosha is not a curse, and it is not necessary to perform the puja if one does not believe in it. It is always advisable to consult a qualified astrologer before performing any puja or ritual.
