The Vamana Purana extolls the glory of the Vimana of Tirumala Venkateshwara Temple in the following verse:
“Vimanam sarva paapagnam sarva lokeshu vishrutam
apraakritam anaadyantam Vaikunttat aagatam mahat ||”
This very Vimanam, which is renowned in all worlds, is extra–terrestrial and without a beginning and an end, is capable of comprehensively destroying all our sins, says the sloka. The word Vimanam can be broken into “Visishta maanam”, meaning the most exalted of all authority (Pramaanam), since it reveals to us the most magnificent of all things to be known (Prameyam), viz., the Lord.
