Gymnosophists were a group of ancient philosophers in India who believed in living a simple life that involved practicing yoga, meditation, and naturalism. While "gymnosophists" is a unique word that is rarely used, there are a few synonyms that can be used in its place. These synonyms include ascetics, sages, yogis, hermits, and holy men. These terms describe individuals who have chosen to detach themselves from the material world and focus on achieving spiritual enlightenment. Whether they are called gymnosophists or any of these synonyms, the core principles of simplicity, meditation, and naturalism remain the same.
