Kartar Singh forcefully advocated for returning to India . Then he himself sailed for Colombo (Sri Lanka). In those people returning from America and going to Punjab were quite often safely. But Kartar Singh did. He dedicated himself to the Party wholeheartedly. They lacked organization. Somehow that was created. In December young Maratha revolutionary Vishnu Ganesh Pingle also reached India. Through their efforts Shachindra Nath Sanyal and Ras Behari also came to Punjab. Kartar Singh was everywhere - if there was a secret meeting in Moga, he was there, next day, message was to be spread among the students in Lahore, he would be the first to be there. Next, the efforts were being made to have an alliance with Ferozepur Cantonments soldiers or there was a need to go to Calcutta for acquiring the arms. He would go everywhere. But there was no money. For that Kartar Singh suggested armed robbery. Many of his colleagues were dumb-founded at the suggestion. He asked them not to worry, told them that even Bhai Parmanand is in favor of robberies. He was given the job to confirm this assertion. Next day he told his colleagues that he had asked him and had his consent. He could not bear the thought that due to the lack of finances, there should be a delay in launching a revolution.
One day, they went to a village for the purpose of carrying out a robbery. Kartar Singh was their leader. While robbery was in progress, there was a beautiful young woman in the house. Seeing her a heinous thought came in the mind of a sinner. He forcefully grabbed the woman by the hand. The woman shrieked out of fear. Kartar Singh immediately took out his pistol, reach that person, and place the pistol on his forehead, disarmed him and shouted, "You wretched man, your crime is very serious, you should be punished to die for that. But the circumstances force us to forgive you. But you fall on the feet of this woman, ask her forgiveness by saying, my sister, forgive me please. Then forgiveness for this fall of mine, If they forgive you, we will let you remain alive, otherwise you shall be shot dead." He obliged. The matter had not gone too far.
Seeing this, eyes of the mother and her daughter were filled with tears. In an affectionate tone the mother said to Kartar Singh, "Son, you seem in such a heinous work? Kartar Singh was deeply moved. He said, "Mother, we are not doing this because of greed for money. In money for arms. How else can we get that? Mother, we have been forced to do this for the great goal (of India's freedom)." It was a very painfully moving scene. The mother spoke again, "We have to marry this girl away. It would be nice if you could leave some for that." Kartar Singh placed all the money before the mother and said, "Take whatever you want." The mother took some money, placed the rest in the bag of Kartar Singh and gave him blessings, "Go, my son, may you succeed in your mission." This episode shows that even when Kartar Singh was involved in such a dangerous job as robbery, his heart remained pure filled with pious thoughts and emotions.
