The term "bodhi leaf" refers to the leaf of the Bodhi tree, which is sacred in Buddhism. This tree, scientifically known as Ficus religiosa, is renowned for being the site where Siddhartha Gautama, who became the Buddha, attained enlightenment. The shiny, heart-shaped leaves are often a symbol of knowledge and spiritual awakening.
The word "bodhi" comes from the ancient Indian word "bodhi," meaning "awakening" or "enlightenment." It is derived from the root "budh," which means "to awaken," "to know," or "to perceive." The Bodhi tree, therefore, symbolizes the enlightenment achieved by the Buddha.
