Buddhism
Buddhism is treated as a proper noun and is typically used as an uncountable noun when referring to the religion or philosophical system as a whole. It carries a connotation of mindfulness, peace, and spiritual discipline, distinguishing it from theistic religions by its focus on personal enlightenment and the cessation of desire.
In academic or sociological contexts, the term may be used to describe various schools of thought (such as Theravada or Mahayana), but the word itself remains singular and uncountable in standard usage. It is never pluralized to describe multiple versions of the faith.
Meanings
A large-scale religion and philosophical system based on the teachings of Siddhartha Gautama, focusing on the elimination of suffering through enlightenment and the practice of meditation and ethical living.
He spent several years studying Buddhism in Tibet.
