"For Hindus, Namo is God's name," Parrikar said during question hour, responding to a question from Congress legislator Aleixo Reginaldo.
The Bharatiya Janata Party leader quoted a Sanskrit phrase "Namo Vasudevaya namaha" and said "Namo means namaskar".
Parrikar said the word "Namo" invoked the name of Hindu deity Lord Vishnu.
At this point, Lourenco said Parrikar was actually equating Gujarat Chief Minister Narendra Modi - who is also popularly referred to as NaMo - to god.
But Parrikar said the other NaMo, to which Lourenco was referring, was gearing up the country to bid goodbye to the Congress.
"In a way, that NaMo is saying namaskar to the Congress," the chief minister said.
