In the heart of the Cauvery delta lies Alangudi, the sacred "Guru Sthalam" dedicated to Lord Jupiter (Guru Bhagavan). Jupiter is the most auspicious of the nine planets, representing wisdom, wealth, marriage, and progeny. The presiding deity, Lord Shiva, is worshipped as Abathsahayeswarar, the one who saved the world by consuming poison during the churning of the cosmic ocean. However, the focus for pilgrims is the shrine of Dakshinamurthy, where Jupiter is worshipped with yellow flowers and chickpeas (Garbanzo beans). Thursdays are exceptionally busy here, as devotees believe that worshipping Guru during his auspicious day brings immediate relief from financial hardships and delays in marriage. The temple’s energy is scholarly and peaceful, reflecting the nature of the "Teacher of the Gods." A visit to Alangudi is a must for anyone seeking growth in career and a prosperous family life during their Navagraha yatra.

The Naganathaswamy Temple at Thirunageswaram is the legendary abode of Lord Rahu. This temple is famous worldwide for a unique miracle: when milk is poured over the deity of Rahu during Abhishekam, it turns a distinct blue colour as it flows over his body, reverting to white once it leaves the idol. Rahu is the "Shadow Planet" associated with worldly desires and sudden changes. Worshipping here during Rahu Kaalam (an auspicious time of day) is believed to protect devotees from the "evil eye," poisonous bites, and the malefic effects of Sarpa Dosha. The temple is a masterpiece of Chola architecture, featuring vast halls and detailed sculptures of serpents. It is an essential stop for those looking to clear obstacles in their career or personal life. The combination of its architectural beauty and the visible miracle of the blue milk makes it a high-interest point for international tourists and pilgrims alike.

As the only temple in Tamil Nadu dedicated exclusively to the Sun God, Lord Surya, it holds immense astrological significance.

Devotees visit this sacred site to seek relief from Surya Dosha, praying for physical health, professional success, and leadership qualities. The temple is famous for its "Kol Vinai Theertha Vinayagar," a shrine to Ganesha who must be worshipped first to remove obstacles. Pilgrims offer red flowers and wheat, performing rituals to harness the life-giving energy of the Sun. Whether you are interested in Vedic astrology or ancient South Indian history, Suryanar Koil provides a powerful start to your spiritual journey through the Navagraha circuit.

The Agneeswarar Temple in Kanjanur serves as the spiritual home for Lord Sukra (Venus).

The temple's legend involves the sage Parasara and the fire god Agni, lending the site a mystical, ancient aura. For travellers on a private temple tour, Kanjanur offers a quieter, more meditative experience compared to the larger shrines.

It is also the world-renowned hub for Naadi Astrology, where ancient palm leaf manuscripts predict the future. Travellers often participate in the "Siddhamirtham" tank ritual, where a holy dip is said to wash away sins and heal the body. For those with Chevvai Dosha (Mars affliction) affecting marriage or property matters, offering salt and pepper at this shrine is a traditional remedy.

The Swetharanyeswarar Temple at Thiruvenkadu is the revered site for Lord Budha (Mercury). Known as the "Kashi of the South," this temple is famous for its three sacred tanks and three presiding deities. Budha is the planetary lord of education, business, wisdom, and communication. Students and entrepreneurs flock here to perform special pujas to sharpen their intellect and ensure success in commercial ventures. The temple also houses a fierce yet protective form of Shiva known as Aghora Murthy, who is said to have vanquished demons at this very spot. Architecturally, the temple showcases the grandeur of the Chola era with intricate stone carvings and expansive courtyards. Visiting Thiruvenkadu is considered essential for those undergoing Budha Mahadasha, as it helps in mitigating communication hurdles and nervous disorders.

Located near the coast, the Naganathaswamy Temple in Keezhaperumpallam is dedicated to Lord Ketu (the South Lunar Node). Known as the "Gnana Karaka" or the provider of spiritual wisdom, Ketu is the planet of liberation and detachment. The temple legend describes Ketu worshipping Lord Shiva after the churning of the ocean to gain divine forgiveness. Devotees visit this shrine to seek relief from "Ketu Dosha," which is often linked to health issues and spiritual confusion. Offering multi-colored clothes and horse gram is the traditional way to appease this shadow planet. The temple is smaller and more intimate than the others, providing a perfect conclusion to the 9 Planets pilgrimage. A visit here is said to grant a clear mind, spiritual growth, and prosperity for the family. Including Keezhaperumpallam in your Viator or Tripadvisor tour package offers travellers a sense of completion and divine protection at the end of their sacred circuit.

Thirunallar Saniswaran Temple is perhaps the most famous and feared temple in the Navagraha circuit, dedicated to Lord Shani (Saturn). Located in Karaikal, this is the only place where Saturn is said to have lost his power over King Nala, making it the supreme site for relief from "Sade Sati" (the seven-and-a-half-year Saturn cycle). Before entering the temple, pilgrims traditionally bathe in the Nala Theertham (sacred tank) to wash away bad luck and "Karma." Lord Shani is worshipped here as a granter of boons rather than a punisher, especially for those who approach him with humility. The temple sees a massive influx of devotees during Sani Peyarchi (Saturn Transit). Offering black sesame seeds and lighting gingelly oil lamps are the primary rituals performed here. For any traveller, the atmosphere of Thirunallar is electric with faith, marking it as a critical destination for those seeking protection and perseverance.
