The Hare Krishna mantra, also referred to reverentially as the Mahā-mantra, is a 16-word Vaishnava mantra mentioned in the Kali-Saṇṭāraṇa Upaniṣad. In the 15th century, it rose to importance in the Bhakti movement following the teachings of Chaitanya Mahaprabhu. This mantra is composed of three Sanskrit names – "Krishna", "Rama", and "Hare".

A. C. Bhaktivedanta Swami Prabhupada (1896–1977) was a spiritual, philosophical, and religious teacher from India who spread the Hare Krishna mantra and the teachings of “Krishna consciousness” to the world. Born as Abhay Charan De and later legally named Abhay Charanaravinda Bhaktivedanta Swami, he is often referred to as “Bhaktivedanta Swami”, "Srila Prabhupada", or simply “Prabhupada”.
