शड्खदुन्दुभिनिर्धोषैविविधैर्गीतवादितै: । क्रियमाणैर्न कम्पेत युक्तस्यैतन्निदर्शनम्

याज़्ञवल्क्य उवाच
A yogin’s genuine concentration is tested by disturbance: even intense external noise and entertainment do not shake the mind. Unmoved steadiness is the practical sign of mature samādhi and inner discipline.
Yājñavalkya is describing how to recognize true yogic absorption. He gives a vivid example—conches, drums, singing, and instruments—to show that the collected practitioner remains undistracted despite sensory commotion.
