Lavishing praise on PM Modi on his 67th birthday, Mr Shah said the Prime Minister's life in many ways was a "personification of the spirit of India" and claimed his sensitivity towards the aspirations of the poor had led to "historic poverty alleviation initiatives taking shape at a scale unheard of in the history" of India.
Under the Modi government, Mr Shah said, honest taxpayers, a majority of whom belonged to the middle class, felt they were valued following crackdowns against black money and corruption through various measures, including demonetisation and the benami law.
Opposition parties had sharpened their criticism of the government's claims about demonetisation after the RBI said over 99 per cent old notes were deposited in banks but the BJP insisted it had increased transparency and expanded the formal economy.
"India remembers Sardar Patel for the territorial integration of our nation and we recall the role of Babasaheb Ambedkar in our social integration. Through initiatives starting from the Jan Dhan Yojana to the GST, Narendra Bhai has set the ball rolling for the economic integration of India," Mr Shah said in a blog.
Targeting the Prime Minister's critics, he said PM Modi had ruffled several feathers by his action against the corrupt and status quo- "after all, years of privilege of a select few are now over and the poor are now getting their due".
PM Modi's heart, he said, "beats for the poor, downtrodden, marginalised and the farmers of India". Mr Shah added that the PM's deep concern for their welfare had motivated him to immerse himself in nation building from a very young age. "India First is a belief that Narendra Bhai has lived at every point of his life," Mr Shah wrote.
People saw PM Modi as a compassionate leader, he said. "They see him as their own, a person working round the clock for their and the nation's welfare, without any self-interest. His popularity has transcended all boundaries," the BJP chief said.
He added that he first met PM Modi as a young BJP worker and neither of them was drawn to power as the saffron party then was far from the force it later became. What mattered, he said, was that they devoted every moment of their time for India's welfare.
"We will continue to serve the nation and support him (Modi) as he takes India to new heights of success and glory," Mr Shah said citing the Mudra scheme, Jan Dhan accounts, surgical strikes and demonetisation to underline PM Modi's resolve and commitment to the country's welfare.
