The Royal Seat
Vīṭṭirunta Tirukkolam (Tamil: vīṭṭu = abode/elevated position + irunta = being seated + tirukkolam = sacred form; 'the sacred form of sitting in exalted state') is the posture in which Bhagavān is enshrined seated in royal composure — Āsīna (seated) in Sanskrit Āgamic terminology.
The Seated Deities
Yoga Narasimha at Śoḷiṅgapuram is a celebrated seated form in the Divya Deśam tradition. The mūlavar Varadarāja Perumāḷ at Kāñcīpuram is in a standing posture and should not be cited as an example of vīṭṭirunta tirukkolam.
Theological Meaning
The seated posture represents Bhagavān's stable, sovereign presence — the king who is always 'in court,' always available to hear the petitions of devotees. Unlike the reclining posture (ultimate ease) or standing posture (readiness to act), the seated form combines both: established sovereignty with attentive grace.
