Shakyamuni Buddha is not a Buddha.
Shakyamuni, the founder of Buddhism, was born in Lumbini, in present-day Nepal, and was a prince of the Shakyamuni clan. As a teenager, he felt the vagaries of the world and pondered the way out of life's suffering. At the age of 29, he became a monk and practiced. After attaining enlightenment, he preached the truth of his enlightenment to the masses in the central Ganges Valley of India, and gained more and more followers, thus forming an order and forming Buddhism. At the age of 80, he attained Nirvana in the Detention of Naga. Therefore, Shakyamuni was a historical figure, and his life deeds and ideas and doctrines are well documented.
The Buddha is one of the concepts in Buddhism, usually referring to the ** and basis of the Dharma taught by Shakyamuni Buddha. In Buddhism, "as it comes" means "to come as it is", indicating that the Dharma spoken by Shakyamuni Buddha is true and in line with reality. Therefore, the Buddha is not a specific personified image or deity, but an honorific title and evaluation of the teachings of Shakyamuni Buddha. Autumn and Winter Check-in Challenge
