अथ आरम्भावस्था ब्रह्मग्रन्थेर्भवेद्भेदो ह्यानन्दः शून्यसम्भवः । विचित्रः क्वणको देहेऽनाहतः श्रूयते ध्वनिः ॥ ४.७० ॥

atha ārambhāvasthā brahmagrantherbhavedbhedo hyānandaḥ śūnyasambhavaḥ । vicitraḥ kvaṇako dehe'nāhataḥ śrūyate dhvaniḥ ॥ 4.70 ॥

When the Brahma granthi (in the heart) is pierced through by the Prânâyâma, then a sort of happiness is experienced in the vacuum of the heart, and anâhat sounds, like various tinkling sounds of ornaments, are heard in the body.
