Rabindranath had to face a new problem when he was busy with his ailing daughter Renuka. He came to Calcutta keeping his daughter Renuka, on 12 Bhadra (29th Aug,1903) Almorah. He got a letter from Mohit Chandra complaining about his initiative of getting his son, Rathindranath, married in the month of Phalgun. The basis of this information was hear say. In reply to this letter, Rabindranath said,
Don't get tensed. Coming 3/4 Phalgun, there is no chance of Rathi's marriage. Perhaps, I told some body, during discussion, that I want take leave by handing over my duties after getting Rathi married. This might have reached the parents of would-be bride and they are always showing their eagerness but I answered all of them in the negative. Even they asked Rathi about his opinion in this matter. By this way it floated in the air.
Mohit Babu was satisfied with this answer.
Rathi was married with Pratima Devi (1893-1969), the elder sister of Gaganendranath and widow daughter of Shesendrabhushan Chattopadhyay, on 14 Magh 1316 (27 Jan 1910). It is said that Mrinalini Devi expressed her willingness to get her as her daughter-in -law after the birth of Pratima. It was revealed from a letter of Rabindranath that he also approved it. But knowing that they are not eager to get him married just now, the parents of the bride had to give up the idea.
Purnima Chattopadhyay, the daughter of Gaganendranath wrote;
At the time of marriage Pratma was only 11 years old. They got the invitation of her 'bed of flowers' at the middle of 1310, Bangabda. But within two months of her marriage her 1st husband, Nilanath Chattopadhyay, died after being drowned in the Ganges.
Santiniketan was having shortage of teachers at that time. Rabindranath suggested that if suitable teacher was not available, Rathi and Santosh might be utilised in teaching students of lower classes.
Having learnt that Ranidi had come to Calcutta, Mira Devi came to Jorasanko to see her and wrote;
" I can't forget how lean and thin she has become, which is evident from his pale smile.She called me and handed over all her toys to me. On their way to Calcutta her father bought for her." I had gone to Mejoma after meeting her. I do not know hen she was relieved of all her pain and agony. I heard that just before her death she asked her father, to recite ' Ong, Pita nohasi Balo.' When they were in Hazaribagh her father recited sloka from Upanishad every day.
Rathindranath and Shamindranath came on 19 Bhadra (5 Sep) to bid her last visit. after 9 days from this date , 28 Bhadra (14 Sep) Renuka Died.
Prasanta Mahalanabish wrote, "after the death of his 2nd daughter, Rabindranath told him.It was Swadeshi movement then."
