I was listening to the discourse by Sri Velukuddi Swamy on Thiruppavai. The meaning of Vaiyathu Vazhvirgal, as explained by Swamy, is that we can convert the place we live by our actions.
I have copied a translation of the above pasuram, from "Sri Andal Thiruppavai Website" and it English meaning below. For those who are interested, here is the link:http://namperumal.tripod.com/TPMain.htm
At her cordial invitation a huge crowd gathered and the
wonder-struck ANDAL exclaims,"in this ignorance-spreading
world, are there so many interested in Emancipation!".She
proceeds to prescribe "dos" and "don'ts"( which actually
are the SAMBHAVITA SWABHAVA,the natural characteristics
of the Adhikari).
While we appear to be performing this vow for getting
rain,in reality it is different.She stresses the words
"NAMUM NAM Pavaikku"- NAMUM- WE are quite different
from others; we long for His company and firmly believe
that He alone is the Means for achieving it. NAM Pavai-
Indrajit did a malefic rite to put an end to Rama;but
OUR beneficent rite is for securing Lord's and His
World's prosperity and happiness.
The SriVaishnavite Code of Conduct as prescribed by
her is as follows:
Recite the Samskrita and Dravida Veda which sings the
glory of the Feet of the Lord reclining on the Serpent
in the Milky Ocean,all the while thinking about one's
Redemption.
Eschew all carnal and even worldly desires like eating
ghee,drinking milk etc.
Bathe early in the morning.Don't adorn your eyes with
collyrium,or your hair with flowers till the completion
of the vow;meaning thereby that a SriVaishnava needs
decoration etc only when he is in union with the Lord.
Never indulge in an act which was not practised by our
righteous minded ancestors.Bharata refused the kingship
though granted by his father and permitted by Rama
on the grounds that the tradition of Solar Kings did
not permit a younger son to rule when the elder was
living.
A SriVaishnava should not speak ill of others or
even think about it (which is tantamount to reporting
it to the God inside the heart,thereby ensuring their
fall);Sita never uttered a word to Rama about the
illtreatment by the Rakshasis.
He should ever be ready to do charity and impart
knowledge about God to all those who need it.
In short he should constantly be thinking about his
upliftment and keep his mind filled with peace and
happiness.
