A large number of daily newspapers from various provinces, and senior leaders had initiated movements for his release. Dr. Annie Besant, among others, met the Viceroy for this purpose. As he had taken a vow not to consume food without worshiping Jain Tirthankar's idol, he fasted in the jail for seventy days, and broke fast only when Mahatma Bhagwan Din was successful in having the idol brought there, a unique occurrence in the history of jails.
One of his revolutionary cohorts, Moti Chand Jain, from Maharashtra, was sentenced to death. Shri Sethi had married one of the daughters, out of the three sons and three daughters from his wife Gulab Devi, to Maharashtrian Brahmin.
His son Prakash was on his death bed in 1923, at the young age of twenty-five. Shri Sethi received a telegram urging him to journey to Jodhpur immediately. Simultaneously, he received a telegram from Pt. Sunder Lal, requesting he travel to Bombay to address a meeting. The bonds of affection could not dissuade his dutiful mind, and he hastened to Bombay.
Before the start of his lecture he received the telegram informing him of the death of Prakash. Unperturbed outwardly, he gave his lecture, to the great surprise and mixed sorrow of the large audience which was aware of the sad demise.
