The Missionaries of Charity selected Sister Nirmala Joshi as the successor to the beloved Mother Teresa, who had passed away just months earlier. The decision came during the general chapter of the congregation convened in Kolkata, India, where members assessed the future direction of the organization dedicated to serving the underprivileged. Nirmala, a close confidante of Mother Teresa, had already been active within the Missionaries for many years and had demonstrated deep commitment to its values and missions.

Nirmala's appointment was pivotal, considering Mother Teresa's monumental role in shaping the congregation and inspiring humanitarian efforts globally. As the new leader, Nirmala faced the challenge of maintaining the momentum of the organization's activities while also addressing new global humanitarian concerns. Her election was celebrated among the Missionaries, emphasizing a continuity of care and compassion for the marginalized, which defined Mother Teresa's legacy.

Under Sister Nirmala's leadership, the Missionaries of Charity continued expanding their outreach, including establishing new branches and programs to serve impoverished communities. Her leadership style reflected humility and deep spirituality, akin to Mother Teresa's approach. Nirmala was dedicated to ensuring that the principles of service, love, and devotion persisted as the guiding lights of the organization.
