Samputa Kumbhaka is classically defined in texts like the Gheranda Samhita as a method of breath retention involving the simultaneous application of Jalandhara and Uddiyana Bandhas. While the standard practice focuses on the anterior-posterior compression of the thoracic cavity, the variation known as Parshva Samputa introduces a lateral flexion component. This paper explores the physiological implications of Parshva Samputa , hypothesizing that lateral flexion during breath retention creates asymmetric intra-thoracic pressure gradients. The study aims to measure oxygen saturation (SpO2), heart rate variability (HRV), and tidal volume in practitioners performing standard vs. lateral Samputa, proposing that Parshva Samputa may facilitate targeted ventilation of the lateral lung lobes and stimulate the vagus nerve via distinct mechanical pathways.

The term is rooted in Sanskrit, where translates to "side" or "flank" and "Samputa" refers to a "treasure chest" or a hollow space created by joining two parts.

The "box" pressure in standard Samputa stimulates baroreceptors in the carotid sinus. The Parshva variation introduces shearing forces in the thoracic cavity, which may provide a novel stimulus to the vagus nerve as it descends through the neck and thorax, potentially amplifying the parasympathetic "relaxation response."

The findings suggest that Parshva Samputa creates a distinct hemodynamic profile compared to standard retention. While standard Samputa focuses on central (axial) pressure, the lateral variation distributes air flow and pressure differently. This has implications for:

Not to withhold. To contain until the right moment unfolds like a chest opening along its single, silent hinge.
