Adhishtanam of Shri Padma padacharya seen in Shri Ekambareshwarar temple Kanchipuram

 Shri AdiSankara had many disciples and prominent among them were Sureshwaracharya, Padmapadacharya,Hastamala, Thotakacharya. These disciples were giants in their own stead but drew strength from the guidance of their guru and  travelled with Adishankara . At appropriate times they were given charge of his various mutts established by him and contiinued the legacy. I recently came to know from the Kanchi mutt that the samadhis of Padmapada and Thotakacharya  are also in kanchi where they came on hearing that their guru had left his earthly form wished to be interned near his samadhi (as per Kanchi mutt belief and records) . We can find the Adhishtanam of Sri Sureshwaracharya inside the Kanchi mutt( click to see my blog on this acharya)

 

Shri Padmapadacharya

Sri Sankara went to Kasi and by that time, he had a lot of disciples. One of them, Sanandhyaya, was drying the clothes of his Guru and suddenly Sri Sankara called him to the other bank of the river as he needed the clothes urgently. Sanandhyaya, little realising that he would drown, starts walking into the river. However, the Grace of his Guru resulted in a lotus materialising wherever he was keeping his foot. When asked as to how did he cross the river, he says that when his Guru calls, he is not to worry about anything. Sri Sankara named him as Padma Padar (lotus feet).

 Padmapada was the first head of Puri Govardhana matha. He is believed to have founded a math by name Thekke Matham in Thrissur, Kerala. Keralites believe that he was a Nambuthiri belonging to Vemannillom, though according to textual sources he was from the Chola region in South India.

Padmapāda, together with Sureśvara, developed ideas that led to the founding of the Vivarana school of commentators. The only surviving work of Padmapāda known to be authentic is the Pañcapādikā. According to tradition, this was written in response to Shankara's request for a commentary on his own Brahmasūtrabhāsya, and once written was destroyed by a jealous uncle. The surviving text is supposed to be what Shankara could recall of the commentary; certainly, all that survives of the work is an extended gloss on the first four aphorisms.

Padmapadacharya's Guru bhakti was exemplary. 

Once he came to know of his Guru's samadhi in Kanchipuram,

he too rushed back to Kanchipuram and took samadhi at Ekambareshwar temple.

The samadhi temple is known as "Vishnu-eswarar"

and just outside the south gopuram of

the Ekambareshwar temple, Kanchipuram..
