These 2 temples are opposite to each other in the same street of Kanchipuram and are very near to Kanchipuram railway station. Both together are considered as one divyadeshams of Thondanadu .
Here the Lord Vishunu is green colour in sitting posture on Adhiseshan referred as Maragatha Vannar ( maragatham means emerald ) .This is a small temple .
Its said Lord Rama appeared before Brighu Maharishi .
Brighu Maharishi raised many questions regarding Rama avatar why Rama allowed Lanka King Ravana to abduct his wife Goddess Seetha and why he seeked others help as Lord Rama himself was capable of rescuing Goddess Seetha from Lanka King Ravana .
Lord Rama explained to him that his RAM avatar was to make people understand how to lead a dharmic life , the right path , respecting elders , unity between brothers and his good emerges victorious at the end over the evil . It was none other than Lord Shiva who took the form of Lord Anjineyar and Adhiseshan as Lakshmanan .
As he appeared as Lord Rama in this place Brighu Maharishi obliged for the dharshan of Adhiseshan so Adhiseshan appears here as a jyothi (naga Deepam) in the shrine of the Goddess .
Devotees offer tulsi and green clothes to this Lord to avoid the negative effects of mercury ( Buthan ) .
Here the Lord Vishnu is coral red in colour (coral means pavalam in tamil) also known as Paramapathanathan . The moolavar is in sitting posture on Adhiseshan and the thayar name is Goddess Pavalavalli Thayar . Thirumangai alwar has sung praising this Lord .
Visiting both Lord Pachaivannar and Lord Pavalavannar is considered as worshipping Lord Shiva and Goddess Parvathi .
Goddess Pavalavalli Thayar has a seperate shrine in this temple . Usually Srichakra is installed opposite to Thayar temple or near by here its installed inside the shrine itself . Here the Thayar blesses in 3 forms as Goddess Lakshmi , Chakrarupini and as Goddess Seetha .
