[gowri narayanan]

savinayam-with humility, sada-always, smarAmi- I remember , chAyA devi priya tanayam-the dear son of chAyAdevi
mAyAmaya jagadAyAsa-the worldly worries arising out of maya(illusion),haram-remover.mAhendra-indra, nIlamani-nIlamani(sapphire), hAram-necklace.(I remember saneeswara decked with the necklace of indra neela gem,and he removes the worldy worries arising out of mAya)
shamana sodaram-brother of yama, shanaishvaram-Lord Saneeshvara,amitAnanda_gives boundless joy, harikeshapriyam-dear to harikesa(the mudra of muthayya bhagavatar)kamaniya deham-with beautiful body, kakavAham-his mount is the crow,vimalam-the blemishless one, maruthy bhakta bharana pravInam-the foremost of the saviours of Anjaneya bhaktas, makara kumbha rAshyadhipatim-the presiding deity of the 2 rasis,makaram and kumbham.
(I remember the brother of Yama,the Lord Sani,who gives boundless joy.he has a beautiful body,a crow for a mount,he ,the spotless one,skilful in protecting the devotees of maruthi and the presiding deity of the 2 rasis,makaram and kumbham).
