[Advaita-l] virATa, virAja, svarATa

[Shrinivas Gadkari]

Namaste,
I would like to ask if list members can shed light on three technical terms that often occur in the vedic literature, especially bhAgavatam: virATa, virAja, svarATa
Notes.1. virATa, and virAja occur in mantra 5 of puruSa sUkta also2. svarATa occurs in the very first shloka of bhAgavatam, and also    elsewhere in the same text.
