The Dashavatara Stotram of 13 verses is on the ten popular incarnations of the Lord -
Matsya (fish), Kurma (tortoise), Varaha (boar), Narasimha (man+lion), Vamana (short man),
Parashurama (the Rama with the axe) Rama, Balarama, Krishna and Kalki.
Shri Venkatesha (Vedanta Deshika) starts the first verse indicating that the Lord and the
Goddess both take incarnations together. The next 10 verses recounts each of the incarnations
and one more verse that references all of them together. The final verse wishes the reciter
all the benefits.
The exploration here is to get at the meanings of each of the words, investigate roots and related words.
