Lalaji was not merely an outstanding politician but also an able writer. The biographies he wrote in Urdu are memorable. He wrote the biographies of the patriots Mazzini and Garibaldi who unified Italy. He also wrote outstanding books about Indian great men Shivaji, Sri Krishna and Dayananda Saraswati. The books on Mazzini and Shivaji contained passages, which encouraged people to fight for freedom. So the government even thought of arresting Lalaji.
Lalaji was opposed to the recommendations of the University Education Commission. The commission, recommended Government control of education and set forth difficult standards for starting private schools. Punjab was adversely affected by the commission because the Arya Samaj was extremely active in the field of education. After the commission, it became impossible for the people to have any say in their children's education. Lalaji declared that "the Government by these new regulations has made it almost impossible for the Private Education Societies to start schools or improve them. People are compelled to deduce that. the Government does not want to spend money for educational work, nor can endure that Indians should voluntarily undertake this work by spending money, unless the Indians hand over their money and efforts to the Government. It would have been impossible for institutions like the Metropolitan College, Calcutta College, Fergusson College, Poona and D.A.V. College to come into existence under the present policies.
Lalaji dove headlong in the struggle against partition of Bengal. Along with Surendra Nath Banerjea, Bipin Chandra Pal and Arvinda Ghosh, he galvanized Bengal and the nation in a vigorous campaign of swadeshi. The British Government claimed that partition would make administering the region easier. The leaders saw through this excuse as the age old British policy of divide and rule at work.
Lalaji was arrested on May 3, 1907 for creating "turmoil" in Rawalpindi. 1907 witnessed a high-water mark in the adventurous life of Lalaji. That was a time of revolution when the winds of change were blowing across the country; new ideas and a new zest moved the people. There were riots in Lahore and Rawalpindi. In Meerut preparations were being made to observe the 50th anniversary of the first fight for freedom (1857). Peasants were upset on account of the proposal of the government to increase the water rates in Punjab
Sir Densil lbbotson was the Lieutenant Governor of Punjab. He wrote to Lord Morley, then the minister in the British cabinet who was in charge of Indian affairs: "It appears that some leaders like Lalaji have sworn to drive the British out of India. An attempt is being made to kindle hatred against Englishmen and break the government administrative machinery.
Lalaji went there when he learned that five prominent Indian lawyers had been served notices by the Deputy Commissioner. The District Magistrate banned any public meetings or speeches. Lalaji was to give a speech at Rawalpindi in connection with the served notices. The Magistrate declared the congregation that had come to hear Lalaji's speech seditious. When Lalaji could not stop their arrest, he returned to Lahore to move the Chief Court for the bail of the lawyers.
Those were days when there was a sense of fear in official circles. A poor Indian was murdered. A factual report appeared in newspapers. An attempt was made to foist the guilt on a Punjabi journalist. The people of Punjab protested against the mischief of the government. In addition to this, there were disturbances, because of unjust laws like the Colonial Settlement Act and Land Mortgage Amendment Act and because of increase in the tax on land and water rates. Sir Densil was perturbed. Without any reason he deported Lalaji and with him Ajit Singh (a relative of the great patriot Bhagat Singh) to Mandalay in Burma
On arriving at the Commissioner's office, Lalaji was told that he was under arrest in pursuance of a warrant issued by the Governor General who had decided to deport him. At about 4 a.m. Lalaji was put on a special train that left for Calcutta. Lalaji reached the Diamond Harbor railway station and was put on a ship which sailed for Mandalay fort. Lalaji remained in Mandalay for six months. While in Manadalay two British newspapers charged Lalaji of conspiring with the Amir of Kabul for overthrowing the British Raj in India. People all over the country opposed the unjust action of the government. Tilak wrote in the newspaper 'Kesari'- "if the British rulers act like the Russian Czars, the people of India will have to react as the people of Russia did." Government had to bow to the vigorous protests of the people and the legal profession; it had no choice. Government realized that the deportation order was improper and illegal; it brought Lalaji to Lahore on November 18 and set him free.On his release Lalaji filed law suits against the newspapers for making libelous statements and won both cases.
Lalaji was considered one of the famous trinity of the Congress radicals. The three great men were Lala Lajpat Rai of Punjab, Bal Gangadhar Tilak of Maharashtra and Bipin Chandra Pal of Bengal. The country affectionately called them Lal, Bal and Pal. There was a split between the radicals and the moderates in the Congress organization. Lalaji found that it was not possible to bring about an agreement between the two factions; he therefore kept out of the Congress for a few years.In 1911 he re-entered the Lahore Municipal Council. When he stood for election to the Municipal Council his popularity was immense. Even the deaf, the dumb and disabled' people turned up to vote for him. A dumb voter brought a photograph of Lalaji to indicate that he would vote for Lalaji.
