5.27

स्पर्शान्कृत्वा बहिर्बाह्यांश्चक्षुश्चैवान्तरे भ्रुवोः ।
प्राणापानौ समौ कृत्वा नासाभ्यन्तरचारिणौ ॥

sparśān kṛtvā bahir bāhyāṃś cakṣuś caivāntare bhruvoḥ
prāṇāpānau samau kṛtvā nāsābhyantaracāriṇau

Kṛṣṇa (कृष्ण) continues. He starts a practice. The finite verb is in 5.28. This verse is the two "having done" clauses.

The verse

The outer contacts are set outside, the eye is placed between the two brows, and the two breaths that move inside the nose are made equal.

नेपालीमा

बाहिरी स्पर्शहरू बाहिर राखिन्छन्, आँखा दुई भौंहको बीचमा राखिन्छ, र नाकभित्र चल्ने दुई श्वास समान पारिन्छन्।

Where it sits

5.26 left the quenching standing on every side. These two verses say how the body is arranged while that is so. This verse does not yet say who does it or what he is. The nominatives arrive in 5.28, and the sentence closes there.

Split: स्पर्शान् + कृत्वा + बहिः + बाह्यान् + चक्षुः + च + एव + अन्तरे + भ्रुवोः + प्राण-अपानौ + समौ + कृत्वा + नासा-अभ्यन्तर-चारिणौ

The phrases

sparśān kṛtvā bahiḥ bāhyān (स्पर्शान् कृत्वा बहिः बाह्यान्) is the first act. Having put the outer contacts outside. cakṣuḥ ca eva antare bhruvoḥ (चक्षुः च एव अन्तरे भ्रुवोः) is the gaze. And the eye in the interval of the two brows.

prāṇāpānau samau kṛtvā (प्राणापानौ समौ कृत्वा) is the second act. Having made the two breaths equal. nāsābhyantaracāriṇau (नासाभ्यन्तरचारिणौ) describes those two: they move inside the nose. samau (समौ) and cāriṇau (चारिणौ) are both accusative dual, agreeing with prāṇāpānau (प्राणापानौ).

bahiḥ bāhyān (बहिः बाह्यान्) is recited bahir bāhyān (बहिर्बाह्यान्). bāhyān cakṣuḥ (बाह्यान् चक्षुः) is recited bāhyāṃś cakṣuḥ (बाह्यांश्चक्षुः). cakṣuḥ ca eva antare (चक्षुः च एव अन्तरे) is recited cakṣuś caivāntare (चक्षुश्चैवान्तरे).

Sanskrit in this line

The verse is full of the dual because the body is being talked about in pairs. bhruvoḥ (भ्रुवोः) is genitive dual, "of the two brows," ending --oḥ (ओः). prāṇāpānau (प्राणापानौ), samau (समौ), and cāriṇau (चारिणौ) are accusative dual, ending --au (औ). Two brows, two breaths. A plural ending would turn the brows into a crowd and the breaths into a list. The dual is the grammar of a pair.

Say it back

Give the two kṛtvā (कृत्वा) clauses, and keep the breaths dual. If prāṇāpānau (प्राणापानौ) comes out singular, stay here. The verse is not finished until 5.28.
