EmperumAn during pazham & thEn thirumanjanam. Azhwar says:
"salangoNda iraNiyanathu, agalmArvam keendu

nalangoNda karumugilpOl, thirumEni ammaan
naalthOrum magizhndhinithu, maruviyuRaikOil....." | Periya Thirumozhi 3.9.1
The fourth line ".......magizhndhinithu, maruviyuRaikOil" is repeated in all pAsurams of Periya Thirumozhi 3.9.1-10 which clearly says that, emperumAn as Thiru Vaikunta Nathar is happily(magizhndhinithu) residing(maruviyuRai) in this dhivyadesam.
