There is an idol of the sage at the south western end of the inner courtyard (thirumittam). He is, naturally, in a meditative pose.
“yaSasaa praapta sarvaaSam tapasaa nitaraam kruSam
mahasaa soorya sankaaSam manasaa poorumaaSraye”
I beseech the blessing (aaSraye) of (sage) Puru (poorum) whose fame has reached all horizons (yaSasaa praapta sarvaaSam), who has become extremely thin (nitaraam kruSam) because of hard penance (tapasaa) and who shines like the sun (mahasaa soorya sankaaSam).
