The Sathya Sai International Organization (SSIO) is a free, non-denominational voluntary organization based in 126 countries. Its members come from all faiths and share a common goal: to reach the ultimate goal of realization of their innate divinity by practicing the teachings of love and service taught by their spiritual teacher, Sathya Sai Baba.

At the core of the organization is the individual who believes in the assumption of personal responsibility for ethical transformation through selfless love and service. The membership is free and open to all. Typically, individual seekers of love and peace, drawn by the experiences of friends and family members, come to their local or regional Sathya Sai centers for participation in weekly group spiritual singing together with other devotional and spiritual activities, and also to volunteer in regular service activities such as giving food to the needy, organizing medical camps and medical services, and other forms of civic volunteerism.
