Recalling Rajiv Gandhi's words, Singh said, "Nothing is more important than the unity and integrity of our nation. India is indivisible. Secularism is the bedrock of our nationhood. It implies more than tolerance. It involves an active effort for harmony."
"No religion preaches hatred and intolerance. Vested interests, both external and internal, are inciting and exploiting communal passions and violence to divide India," he said.
Singh said another cause for solemn reflection today is some "disturbing trends" that our country has been witnessing over past few years.
"These unpleasant trends of growing intolerance, communal polarisation, growing incidents of violent crimes propelled by hatred of certain groups and of mobs taking the law in their own hands can only damage our polity," the former prime minister said.
He was speaking at an event by the Rajiv Youth Foundation and presented the 'Rajiv Gandhi Janma Pancha Sapthathi Puraskar' to prominent personalities and organisations who have made valuable contributions to the society for the last one decade.
