Modi, who entered the Upper House during Question Hour just before Chairman Hamid Ansari adjourned the House amid uproar by Congress members and others, walked up to the opposition benches.
After the House was adjourned, he greeted former Prime Minister Manmohan Singh and shook hands with him and then further walked up to Leader of Opposition Ghulam Nabi Azad's seat and shook hands with him too.
The Prime Minister also spread some moments with Congress member Karan Singh and stood with him for a while, before greeting Jairam Ramesh, standing three rows behind.
While moving back to the treasury benches, Modi met CPI leader D Raja on the way and then greeted his own party MPs.
