…….Vaishnavanam yatha sambhuh purananam idam tatha……. Parama Shiva is the foremost of all the Vaishnavas.

Srimad Bhagavatam reveals that ParamaShiva is the foremost of all the Vaishnavas. (SB – 12.13.16) Vaishnavanam yatha sambhuh purananam idam tatha……

Lord Sriman Narayana (Lord Vishnu)- the Supreme Personality of Godhead  is glorified  as Parabhrahmam as everything has emanated from HIM .

All the ancient scriptures like Puranas, Vedas, divya prabhandham clearly mention that Sriman Narayana (Vishnu) alone is the Supreme Lord.  The invocatory verse (thanian) of Naanmugan Thiruvandhadhi starts with “Narayanan padaithaan naanmuganai, naan muganaku eraar sivan pirandhaan…..” ..

meaning that Lord Sriman Narayanan created four faced Brahma who in turn created Siva implying that everything emanates from Mahavishnu.  Lord Krishna says “Vaishnavanam yatha samubhuh:’ meaning ParamaShiva is the best of all Vaishnavas and is very dear to the Lord.    Parama Shiva adorns Ganges-the holy water from Lord Vishnu’s feet in his matted locks on the head and is known as Gangadhara.  He shares with Parvathi devi that he always contemplates on Lord Vishnu while meditating.  He declares to Parvathi devi that uttering Rama naama thrice is equal to recitation of 1000 names of Lord Vishnu.  Lord Shiva tells Parvathi “Aaradhananaam sarvesaam vishnor aaraadhanam param” meaning that the most exalted system of worship is the worship of Vishnu. It is believed that in Varanasi (Kashi),  ParamaShiva whispers Lord Rama naamam in the ear of a person who leaves his body

A true Vaishnava doesn’t seek any material benefit from Lord but always prays for more services and bhaagavatha sambandham.   Azhwars have clearly expressed in their pasurams that we should not waste time worshipping demigods and do offence who worship them.

(Nammazhwar in one pasuram reveals :”matrore dheivam padi adi panindhu…..-instead of worshipping demigods, come to Thirukurugoor and fall at the feet of our Adhipiraan( Lord Narayana ) thus wasting our limited time and should resort to the lotus feet of Lord Narayana 

Andal says “Narayananey namakke parai tharuvan..

”At the same time, Azhwar has emphasised that we must cling to the feet of the devotees to attain the Supreme Lord thus avoiding any sort of offences to any devotees .

It is believed that ParamaShiva was meditating at Badrinath before Lord Narayana manifested here .  Lord Narayana appeared in answer to the prayers of Nara and Narayan parvatham and continued to stay here in between the two mountains on Urvashi peetam.  So, it is believed ParamaShiva moved from this place to Kedarnath.  The Lord blessed that pilgrimage to Badrinath would be deemed to be complete only after visiting Kedarnath.  As it may not be possible for everyone to visit Kedarnath which is comparatively on a higher altitude and considering the strenuous journey one has to undertake.

Perumal sports this on one day for a muhurtham.(48 minutes).  As per the sthalapurana, Perumal has given  a place on HIS chest to Shiva.  As he is the Lord of the Universe including Shiva , he dresses like Shiva.  Another reason is during Mughal invasion, to prevent massacre, this Lord was transported to Thiruvaanaikaaval (siva temple) and was kept in safe custody.  As a token of remembrance of this incident, at the behest of the devotees, Lord agreed to give darshan as Shiva for a muhurtham.  .
