स्पर्शान्कृत्वा बहिर्बाह्यां श्चक्षुश्चैवान्तरे भ्रुवोः ।प्राणापानौ समौ कृत्वा नासाभ्यन्तरचारिणौ ॥
sparśānkṛtvā bahirbāhyāṃ ścakṣuścaivāntare bhruvoḥprāṇāpānau samau kṛtvā nāsābhyantaracāriṇau
Having put outside of himself all outward touches and concentrated the vision between the eyebrows and made equal the prāṇa and the apānau moving within the nostrils, having controlled the senses, the mind and the understanding, the sage devoted to liberation, from whom desire and wrath and fear have passed away, is ever free.
Gītā 5·27All of them are processes which lead to the inner trance of Samadhi, …Are we to suppose that the Gita gives this process in that sense as the last movement of a release by dissolution or only as a special means and a strong aid to overcome the outward-going mind?… We shall find reason to regard it as both a special means, an aid, and at least one gate of a final departure, not by dissolution, but by an uplifting to the supracosmic existence. For even here in this passage this is not the last word; the last word, the finale, the climax comes in a verse that follows and is the last couplet of the chapter.
