I wanted to share an unexpected experience I had during a yoga class, specifically a class that included pranayama practice, under the guidance of a particular teacher. This wasn’t something I sought out, and it hasn't repeated since, but it left a strong impression.

During the session, I distinctly felt what could be described as the "opening of the third eye." However, the sensation was much more mechanical than subtle, almost as if my forehead was literally opening up. It felt real, but strangely, it wasn’t part of the practice or anything the teacher mentioned. After the session, everything went back to normal; it was just this momentary experience during the practice.

I’ve never come across descriptions of it happening this way in any readings on yoga or meditation. Has anyone else had a similar experience?
