Surjewala, who called on Sinha at the latter's residence, later said no political significance should be attached to it.
"I have deep regards for Shatrughan Sinhaji. Every personal relationship can't be viewed from political prism. Hope media friends understand," the chief spokesperson of the opposition party said in a tweet.
"It was just a social call," he said.
The actor-turned-politician has been critical of BJP's policies and not campaigned for the party in Bihar assembly elections so far.
In a tweet today, Sinha also advised the party leaders to shun approaching issues on the ground like "5-star press meets".
"Time to stop approaching the issues on the ground like standard, half hearted, 5 star press meets," he tweeted.
"Grassroot BJP workers need and deserve respect and we need to reach out to voters with humility...This is the need at the ground level," he said in another message on the micro-blogging site.
