Pusalar was a great devotee of Lord Shiva. Once Pusalar was interested to create a big temple for Shiva, but due to lack of funds, he was unable to do so. Then, Pusalar has built a temple to Shiva in his mind. He followed all the rituals for the construction of the temple, and completed the temple, and selected a holy day for the Samprokshanam ceremony.
The Pallava king who was also a great devotee of Lord Shiva had constructed a Shiva Temple known as Kailasanathar temple at Kanchipuram, and he also selected the same day for the Samprokshanam of his temple. And as per the instruction is given by Lord Shiva in his dream, he postponed the date of consecration and went to Thirunindravur to see the temple built by Pusalar.
But the king could find any temple located at that place. Then he went to Pusalar’s house and informed him about his dream. The saint informed him that the temple was built by him in his heart. The king was amazed by Pusalar’s bhakti and worshipped him. Pusalar consecrated the temple on the selected day and continued his worship till his death, and finally attained Kailasa, the divine abode of Lord Shiva.
