Swami Chinmayananda, the founder of Chinmaya Mission, was a renowned spiritual leader and a visionary who dedicated his life to spreading the knowledge of Vedanta and promoting spiritual growth among individuals. Under his guidance, the Chinmaya Mission has undertaken numerous projects and initiatives to fulfill its mission of "giving maximum happiness to the maximum number of people for the maximum time."

Some of the major projects and initiatives of the Chinmaya Mission are:

1. Chinmaya Vidyalayas: The Chinmaya Mission has established over 80 Chinmaya Vidyalayas, which are schools that provide a holistic education based on the principles of Vedanta. These schools aim to nurture the physical, intellectual, emotional, and spiritual growth of students.
