Bhagavad Gita, Chapter 5, Verse 27

स्पर्शान्कृत्वा बहिर्बाह्यांश्चक्षुश्चैवान्तरे भ्रुवोः । प्राणापानौ समौ कृत्वा नासाभ्यन्तरचारिणौ

sparśānkṛtvā bahirbāhyāṃścakṣuścaivāntare bhruvoḥ | prāṇāpānau samau kṛtvā nāsābhyantaracāriṇau

Translation

Shutting out all external contacts and fixing the sight between the eye-brows, equalising the out-going and the in-going breaths which pass through the nostrils, controlling the senses, mind and intellect, having mokṣa as his highest goal, free from desire, fear and anger — the sage who ever (remains thus) is verily liberated.

— Alladi Mahadeva Sastri

Śaṅkarācārya's commentary

The sound and other sense-objects enter the mind within through the respective organs. These external objects are kept outside when a man does not think of them. A sage (muni) is one who is given to contemplation (manana) and who renounces all actions.
