After the movement of partition of Bengal in 1905, there was a boost in nationalist ideologies and several publications took active and fierce role in propagating them, including Sandhya.  In March 1907, Sandhya elaborated its motto as, "If death comes in the striving, the death will be converted to immortality." In May 1907, Sandhya reported, "People are soundly thrashing a feringhi whenever they are coming across one. And here whenever a feringhi is seen the boys throw a brickbat at him. And thrashing of European soldiers are continuing..." Further it added, "Listen and you will hear the Mother's trumpet are sounding. Mother's son do not tarry, but to get ready; go about from village to village and prepare the Indians for death." In September 1907 Sandhya wrote, "God gives opportunities to all nations to to [sic] free themselves from their stupor and strength to make the necessary beginning." Bramhabandhab wrote in Sandhya on 26 October 1907, a day before his death, "I will not got to the jail of the feringhi to work as a prisoner.. I had never been at any one's beck and call.
