Stool sampling
STERILE, COLD
Subjects were requested to submit stool samples for 3 time points – 2 months before Samyama (T1), immediately before Samyama (T2), and 3 months following Samyama (T3). Stool samples were collected from meditators and control subjects in sterile fecal collection containers. Upon receiving samples from participants, they were packaged with cold packs and shipped overnight. The samples were then stored at -80 ℃ until samples were analyzed.
