In a message on the eve of Flag Day being observed Friday, Purohit said it was an occasion for remembering with pride the valiant soldiers in the Army, Navy and Air Force.
"This is an occasion to remind ourselves of the selfless services of our Armed Forces personnel in protecting our country's territory from the enemies and intruders," he said.
It was also an opportunity to take the history of our great nation to the younger generation in order to nurture patriotism and inspire them to join the armed forces, Purohit said noting that Tamil Nadu had always been a topper in per capita contribution to the Flag Day Fund.
Palaniswami, in his message, highlighted the role played by the defence personnel in guarding the country and assistance extended to the civilian population at times of natural disasters.
He also appealed for generous contributions by the people of the state to "express their patriotism".
