Rajinder Singh (born 20 September 1946) is the head of the international, non-profit organization Science of Spirituality (SOS), also known in India as the Sawan Kirpal Ruhani Mission.

[3] Singh earned his bachelor's degree in electrical engineering from IIT (Indian Institute of Technology) Madras, India and his master's degree in Electrical Engineering from IIT (Illinois Institute of Technology) in Chicago, Illinois.

His training in both disciplines has helped him express age-old spiritual teachings in clear, logical language.

[9] Integrating both meditation and a spiritual curriculum into a traditional academic environment, the foundation's goal is two-fold: first, to produce students whose spiritual potential is developed along with their intellect and physical well-being; and second, to inspire in each student a global view of the world, unobstructed by distinctions of race, nationality, religion, or economic status.

These individual transformations will ultimately bring unity and peace at the community, national, and global levels."

(From a speech, "Moral Dimensions of Leadership" given to the United States Coast Guard Academy) Meditation is a process by which a practitioner comes in contact with the Light and Sound of God already within themselves.

[13] In the Times of India, Singh states, "Human beings are blessed with a special faculty to gain spiritual knowledge.

[citation needed] In his address given to students and faculty at IIT (Indian Institute of Technology) Mumbai, Singh states: “Science and spirituality make a great partnership.

If those interested in spirituality apply the scientific law of testing a hypothesis in the laboratories of their own bodies, they will find results.

[30][31][32] At the Millennium World Peace Summit of Religious and Spiritual Leaders, United Nations, New York City, New York (August 2000), in his address entitled "Nature of Forgiveness and Compassion" Singh stated: "Spirituality is the recognition that behind our outer names and labels, we are souls, a part of one Creator.

In his address, “Building Peace in the World,” he explored the importance of meditation as the way to connect to our soul and to the divinity that exists within us.

Co-sponsored by the Science of Spirituality and over 30 vendors, the festival celebrates the benefits and joys of a vegetarian lifestyle.

[40][41][42] In 2016, Veggie Fest celebrated its 11th year, launching its largest festival to date: Over 800 volunteers from around the world welcomed tens of thousands of visitors during its two-day program.
