This tradition does not treat meditation as a relaxing vibe. It treats it as engineering: a technology of attention with an actual curriculum, refined over centuries. Patanjali lays out eight limbs: how you treat others, how you run your own life, steady posture, control of breath, pulling attention off your senses, concentration, meditation, absorption. The posture part, the one the modern world kept and sold back to you as fitness? Limb three of eight.

The honest note So how should a scientific mind hold chakras, prana, kundalini? The book's own answer: as the yoga shastra's working model of inner experience. A map drawn by practitioners describing what trained attention finds from the inside. It is not an anatomy chart, and nobody should sell it to you as one. Headlines oversell the research too. The practice doesn't need the hype.
