Bhakoot dosha, especially the 6-8 placement (Shadashtak), is considered significant in Vedic astrology as it can bring challenges related to marital harmony, health, or progeny problems. However, there are several remedies that can be performed before marriage to minimize its negative impact:

Maha Mrityunjaya Jaap & Havan:
Performing the Maha Mrityunjaya mantra jaap (chanting the mantra minimum 51,000 times) followed by a havan is considered extremely potent for relieving various doshas affecting health, longevity, and marital harmony. This puja invokes Lord Shiva’s blessings for overcoming obstacles and negative planetary effects.

Katyayani Puja:
Dedicated to Goddess Katyayani, this puja is especially effective for resolving marriage-related doshas and delays. Performing this ritual with devotion is believed to remove obstacles in finding marital harmony and suitable partners. It is best to do this puja during Navratras.

Swayamvara Parvati Homa:
This fire ritual invokes Goddess Parvati’s blessings for marital unity and overcoming astrological challenges in marriage. The mantra chanted during this homa seeks Divine Grace for a peaceful and fulfilling relationship.

Lakshmi Narayana Samuhika Vivah Puja:
This ritual involves invoking the divine couple, Lord Vishnu (Narayana) and Goddess Lakshmi, and symbolically conducting their marriage. It is a powerful remedy for compatibility issues and doshas obstructing marital bliss, especially when performed on auspicious days (like Ekadashi or during special temple festivals).

Consultation with an Expert Astrologer: Sometimes, Bhakoot dosha is canceled due to other positive planetary positions (known as Bhakoot dosha nivaran yogas). Have both horoscopes analyzed by good astrologers for such mitigating factors before proceeding with remedies.
