In Hissar Lalaji started attending the meetings of the Congress Party and became an active worker in the Hissar-Rohtak region. When the Lieutenant Governor visited Hissar, Lalaji pleaded that the Welcome Address to be presented to him should be in Urdu. To satisfy the British officer a speech had already been prepared in English. Lalaji's suggestion made everyone nervous. But without a trace of fear, he presented the Address in Urdu and there by invited the wrath of the British.
He plunged into Gandhi's non-cooperation movement, which in Panjab, under Lajpat Rai's leadership spread like wildfire in the province, and he soon came to be known as "The Lion of Panjab" or "Panjab Kesri". He traveled far and wide in India and his eloquence brought hundreds to the Congress fold. Lalaji injected new life in his countrymen. His writings and speeches were both hard hitting and effective. They swayed those they aimed to reach. He was a crusader, who knew no fear and championed every worthy cause with all the passion of his soul.
He recovered from the wounds left by the British but he remained emotionally scarred at the brutality of the "civilized" British. Why had he been specifically targeted by the British? Why had they lathi- charged against a peaceful gathering. These thoughts racked his spirit till the very end. Lalaji died on November 17, 1928 of heart failure.
