Addressing a gathering at the Parliament House Annexe here, Modi said Vajpayee never compromised on the ideologies of the party and always spoke about national interest.

"For some people, power is oxygen...they can't live without it...A long part of Atalji's career was spent in the opposition benches but he spoke about national interest and never compromised on the ideology of the party.

"For long, the voice of Atalji was the voice of the nation," Modi said.

"I assume that there must be invitations from other ideologies for joining hands to remain in power. Such things must have happened. But he never compromised.

"He was among those who could die for the nation, but would never compromise on the ideologies," Modi said.

Vajpayee wanted democracy to be supreme. He built the Jana Sangh but when time came to rescue democracy he and others went to the Janata Party, Modi added.

"Likewise, when the choice was between remaining in power or comprising on ideology, he left Janata Party and formed the Bharatiya Janata Party" which "has become among the largest of political parties", the Prime Minister said.

Hailing Vajpayee as "the best orator", Modi said "the mind is not ready to believe that Atalji is no longer with us. He was a stalwart loved and respected across all sections of society.

Modi said e would go to Vajpayee's memorial on Tuesday -- his birth anniversary -- to reiterate his commitment to the ideology and path shown by the leader.

Lok Sabha Speaker Sumitra Mahajan, Finance Minister Arun Jaitley, Minister of State for Culture Mahesh Sharma, BJP national President Amit Shah and veteran BJP leader and Vajpayee's contemporary L.K. Advani were also present at the event to release the coin.

Commemorative coins are usually issued to celebrate some special occasion or to mark a special event. They also have been issued as a mark of respect towards some distinguished individuals or monument.

The coin, Modi said, is a small effort to show our respect to the former Prime Minister, "whose life is a message for all of us".

Atal Bihari Vajpayee passed away on August 16 at the age of 93 at the All India Institute of Medical Sciences (AIIMS) here following a prolonged illness.
