In the year 2005, I presented a research paper on Lord Vamana in a 2 day National Seminar on “LORD VAAMANA in Art, Literature, & Religion” held at Mysore during 23-24 March 2015. The paper was titled “Lord Vamana in the Bhagavata Purana”. This paper brings out the meaning of the word Vamana – it does not mean a dwarf – and also details how the Bhagavata Purana glorifies the avatara as such. The link to the paper is as below:
