All of you should take a vow to continually develop the Service (Sevā) Organizations. Let all join in the activities. Treat all as the children of one God. Whomsoever you may serve, consider you are serving God. Then you will experience the Divine. You are bound to have that experience soon. Never give up the organization. Regard it as the breath of your life. This is real penance. Having this firm resolve, become exemplary leaders. This is My sole desire. Swami's love will accompany you everywhere.

The Sathya Sai International Organisation (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. 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 with other devotional and spiritual activities. They also volunteer in regular service activities such as providing food to the needy, organizing medical camps and medical services, and other forms of civic volunteerism.

The premise of Sathya Sai Centers is that they provide a space for a spiritual meeting of like-minded individuals, a communion of people of all faiths who desire to perform good works. In such a space, sincere seekers, students of spirituality, and service-minded volunteers gather for spiritual singing and devotional spiritual activities and to study the teachings of Sathya Sai Baba. The goal of participation is ultimately the transformation of self and society into a place of selfless love, a place where the recognition of the Divinity innate in humanity becomes possible. The living ideal of the SSIO is the cultivation of oneness with others, family, community, nation, and world.

The SSIO consists of about 2000 Sathya Sai Centers. Center activities are coordinated by voluntary organizational leaders working at center, regional, national, and international levels according to the broad guidelines and ideas envisioned by the governing bodies of the organization, the Sri Sathya Sai World Foundation and Prasanthi Council. The most important aspect of the organization though is the fact that every day of the year, somewhere on this earth, a man, woman, or child who desperately needs respite from some material problem like hunger or illness, and equally, a sign of kindness and love, gets both from volunteers of the Sathya Sai Centers. For members of the SSIO, service is not a mere gesture, but something that is rendered voluntarily, wholeheartedly, and with the greatest joy and love. The organization helps sustain, in thoughts, words, and actions, the legacy of love created by Sathya Sai Baba.

The SSIO is governed by the Sri Sathya Sai World Foundation (SSSWF) and the Prasanthi Council (PC). In addition, there are committees appointed by the SSSWF that help in the administration of day-to-day activities.
