The Dwadasakshara Mantra (12-syllable mantra): "Om Namo Bhagavate Vasudevaya" is the most important mantra to be chanted throughout the 12 days.

Gomed (for Rahu) and Lehsuniya (for Ketu) are stones for the shadow planets. These planets represent intense, explosive, and highly chaotic karmic energies. Because they deal with massive, sudden shifts, the gemstones burn through their energy reserves very fast, typically expiring in just 2.5 to 3 years.

Tapasvi Rajyoga forms when Rahu and Jupiter sit together in the 5th or 9th House. Unlike the feared Chandal Dosha, this combination grants immense, specialized knowledge. The person earns massive wealth through deep intellect, such as Data Science, AI, Astrology, research, or foreign languages.

The most effective Beej Mantra for Mercury is "Om Bum Budhaya Namah" (ॐ बुं बुधाय नमः). Chanting this mantra 108 times using a Rudraksha or Emerald mala, especially on Wednesdays, brings excellent results.
