ALWARS AND ACHARYAS

Sriman Narayanan is the first Acharyan in our srivaishnava sampradayam
He in turn gave upadesam of MAHAMANTRA to Nara at Badri sthalam.By chanting
this mahamantra everyone should attain the lotus feet of HIM .
But against his dreams humanbeings still wants only materialistic life
and not intersting to reach HIM.
Hence he came to this earth by taking AVATARAS.except in some avatars
he is not able to convince lot of human beings and his dasavataras are known
to everybody.
Not satisfying himself HE again take some avataras like humans to catch
them as elephants are ised to catch forest elephants and deers too.
These avataras of Him OUR GREAT ALWARS who in turn create,chant and gave
in total 4000 versus pasurams about sriman narayanan.
Though they wrote these pasurams either they have published them to people
or taught to some sishyas i.e deciples to propaganda the same.
Hence this time also He is not able to collect more human beings to his side.
swami manvalamamunigal in his upadesarathinamalai prapandham narrates the alwars:
