Armed with a massive mandate, Modi neverthless faces challenging tasks ahead as he grapples with a weak economy and other problems left behind by his predecessor Manmohan Singh.
A consummate politician and the man of the moment, Modi is known for his bold and unconventional initiatives and is poised to evolve as the ultimate 'game-changer' of Indian politics.
The premiership of Modi, who represents a fascinating turning point in the political history of the world’s largest democracy, promises to usher in dramatic changes and reforms.
During the course of his hectic Lok Sabha campaign, Modi, a four-time Gujarat Chief Minister, told his voters he had been chosen by God to do a "difficult task" and promised to replace the business as usual culture with purposeful governance.
One of the trendiest male politicians in India, Modi, who pulled off what had looked like an impossible feat of winning a majority for BJP on the strength of his persona and a muscular poll campaign, dismisses charges of being authoritarian.
Modi said during the campaign that he believed in team work and that those who worked with him believed that he was strong-willed and decisive.
He accused his opponents of resorting to "vague, non-specific and subjective things like saying that I am authoritarian, jingoistic, divisive". There had never been any serious allegation of corruption, nepotism or incompetence against him, he said.
Modi may be one of the most riled leaders described variously as divisive, polarizing and a Hindutva-hardliner given the backdrop of the riots that had claimed over 1000 lives, mostly Muslims, in March, 2002 under his watch.
But Modi is seen by his supporters as a "strong leader" who will not play the politics of appeasement of any section.
A stocky, bespectacled man with a trimmed white beard, and known for his ascetic lifestyle and enthusiasm for yoga, Modi came under international glare due to the 2002 riots. A brilliant speaker, the Hindutva poster boy turned a fragmented parliamentary election into a presidential-style referendum in an era of coalition politics in the country.
His mandate, crossing caste, region, gender and demography, will make him one of the most powerful Prime Ministers in Indian history.
Born to lower middle class parents in Vadnagar in Gujarat, he has transformed himself from a Hindu nationalist into a decisive corporate-style administrator. He is now at the centre of global thinking, having been labelled "the man who dines alone", a "game changer" and a "poet".
He takes the reins of the country in a culmination of a fascinating journey from an ordinary RSS pracharak and Gujarat's longest serving chief minister. Modi also worked in his family's tea stall, according to a sympathetic biography.
Modi has a formidable reputation as a party organizer, along with an ability for secrecy, which comes from years of training as an RSS "pracharak".
A rank outsider to the 'Delhi club', the Gujarat Chief Minister steamrolled all opposition within and outside to secure for BJP a majority that no party could get after Rajiv Gandhi's '400 plus' victory in 1984.
On the victory path, Modi virtually blanked out all others in the party and became its sole face in a long campaign that started last summer after he was made the campaign chief in Goa.
Undeterred by the sulk of veterans like LK Advani and grumblings of some others, mounted an untiring campaign crisis-crossing the country helping BJP record its finest-ever performance in more than three decades of its existence.
There was more sulk when he was anointed the BJP's prime ministerial face in September but that did not deter him from his mission in getting the BJP-led NDA back to power from where it was dislodged in 2004.
In the beginning, there were doubts whether Modi can equal the charm of Atal Bihari Vajpayee, considered a moderate even by his rivals, in attracting allies.
But the BJP put all its eggs in the Modi basket, a gamble that has paid with Modi attracting more allies pre-poll, including those who had left the NDA blaming him for the 2002 riots. In the 12 years he had been chief minister in Gujarat, Modi consciously crafted an image of a man with an alternative vision of governance for a country caught in a policy paralysis in the last few years.
With his development model as his campaign plank, he made an instant connect with young voters, middle class and those in rural areas yearning for a change. But occasionally there were hints of polarizing voters raking up pet issues of the saffron forces.
A master strategist, Modi has come a long way from selling tea at railway station for his father to emerge as a pan India leader. There are many of his critics who contest his claim of having sold tea.
In a state the sangh parivar called the "Hindutva laboratory", the chief minister consolidated his image as a hardliner and election after election he delivered results for the party--scoring a hat trick last year in the Assembly polls.
In his attempt to reach out to minorities, especially the Muslims, he consciously shed the hardliner approach and focused on development, including those of the poor in the Muslim community.
He battled all odds to emerge as BJP's prime ministerial candidate piping Advani among others. But since then he had run a very clever, spirited and never-before-seen high-tech campaign addressing more than 450 rallies across the country.
Having been born in a backward 'Modh Ghanchi' (oil crusher) community in historical Vadnagar town of Mehasana district years, the rise of Modi is phenomenal. However, his status as a person belonging to backward community itself has also been contested.
The RSS pracharak, who was loaned to BJP in 1985, remained a backroom party office-bearer and key strategist till he was made Chief Minister of Gujarat to replace Keshubhai Patel in October 2001. Just five months after he took over as Chief Minister, Modi controversially came into limelight in the wake of 2002 riots triggered after 59 'Kar Sewaks' were killed in a fire in a compartment in Sabarmati Express train incident on February 27, 2002.
His detractors accused Modi of inaction during riots, but all the subsequent investigations, including one directly under the supervision of Supreme Court-appointed Special Investigations Team (SIT) and subsequent court ruling have given clean chit to Gujarat Chief Minister.
Modi has also been under repeated attack over alleged fake encounters and his close aide Amit Shah is under a cloud in a few of these.
But Modi mastered the art of converting adversities into opportunities. He did some pioneering work in Gujarat to win subsequent elections in 2007 and 2012 on developmental politics decimating Congress.
He has been claiming credit for bringing the issue of development to centre stage in his efforts to reinvent himself.
After the Supreme Court-appointed SIT gave a clean chit to him in the 2002 riots, Modi undertook a 'Sadbhavna' fast to reach out to Muslims of Gujarat as some kind of penance by going on a three-day fast in Ahmedabad. Similar fasts were also undertaken by him in Gujarat's other cities.
Modi has been tom tomming Gujarat model of development, including his government's 'open arms' welcome pro-industry, which has its own share of critics.
Business leaders have pitched for him as Prime Minister as they feel he is a decisive leader especially against the backdrop of policy paralysis that marked the UPA II's tenure.
In one of the events, he refused to wear a skull cap offered by a Muslim cleric, an issue that had cropped up in the current elections. But he fobbed off all criticism saying he would not follow his rivals' politics of symbolism.
Inspired by life and teachings of Gautam Buddha and Swami Vivekananda, Modi had left his Vadnagar home as a youth and joined the RSS as a pracharak. At a tender age he used to sell tea, first at the railway station of his village where his father had a tea stall and later at the canteen of Ahmedabad city bus terminal.
The scale of the 63-year-old Modi's electoral triumph devastated his rivals and even his most ardent supporters. On the way he has re-written the rules of the electoral game with a brilliant though expensive campaign.
