Which Imperishable the knowers of the Veda declare, which the renunciants free from passion enter, desiring which they practise brahmacarya, that goal I shall declare to you in brief.

पुनरपि वक्ष्यमाणेन उपायेन प्रतिपित्सितस्य ब्रह्मणो वेदविद्वदनादिविशेषणविशेष्यस्य अभिधानं करोति भगवान् —
यत् अक्षरं न क्षरतीति अक्षरम् अविनाशि वेदविदः वेदार्थज्ञाः वदन्ति, ‘तद्वा एतदक्षरं गार्गि ब्राह्मणा अभिवदन्ति’(बृ. उ. ३ । ८ । ८) इति श्रुतेः, सर्वविशेषनिवर्तकत्वेन अभिवदन्ति ‘अस्थूलमनणु’ इत्यादि । किञ्च — विशन्ति प्रविशन्ति सम्यग्दर्शनप्राप्तौ सत्यां यत् यतयः यतनशीलाः संन्यासिनः वीतरागाः वीतः विगतः रागः येभ्यः ते वीतरागाः । यच्च अक्षरमिच्छन्तः — ज्ञातुम् इति वाक्यशेषः — ब्रह्मचर्यं गुरौ चरन्ति आचरन्ति, तत् ते पदं तत् अक्षराख्यं पदं पदनीयं ते तव सङ्ग्रहेण सङ्ग्रहः सङ्क्षेपः तेन सङ्क्षेपेण प्रवक्ष्ये कथयिष्यामि ॥ ११ ॥
In plain words
Once more the Lord sets out to name Brahman — the very thing to be reached by the means he is about to describe, the reality marked out by descriptions beginning with "what the knowers of the Veda declare":
'That Imperishable' — it never decays, so it is called imperishable, undecaying: this is what those who truly understand the Veda, not merely recite it, declare. As the scripture itself says, 'That, Gārgī, is this very Imperishable which the brāhmaṇas speak of' (Bṛhadāraṇyaka Upaniṣad 3.8.8) — and they speak of it only by stripping away every attribute, saying 'not gross, not subtle,' and on and on like that. And there is more: it is what ascetics — people given wholly to inner effort, renunciates who have let passion simply depart from them — enter into fully once true seeing has dawned. And it is what seekers, wanting to know it, undertake a life of celibate discipline under a teacher for. That state — the one called the Imperishable, the very thing worth reaching — I will now tell you, Arjuna, in brief.
Close to the Sanskrit
Once again, by the means about to be stated, of Brahman which is sought to be attained, which is the substantive qualified by the attributes beginning with 'the declaring of the knowers of the Veda' — the naming the Blessed Lord makes —
'That Imperishable': it does not perish, therefore 'imperishable,' undecaying; the knowers of the Veda, those who know the meaning of the Veda, declare — as per the scripture, 'That indeed is this Imperishable, O Gārgī, which the brāhmaṇas declare' (Bṛhadāraṇyaka Upaniṣad 3.8.8) — they declare it by negating every particular, saying 'not gross, not subtle,' and so on. Moreover — 'they enter,' that is, they enter fully, once right vision has been attained — which the ascetics, those given to striving, renunciates, free from passion — passion has departed from whom, they are 'free from passion' — enter into. And desiring which — 'to know' is to be supplied to complete the sentence — they practice brahmacarya under a teacher, observe it — that state of yours, that state called the Imperishable, worthy to be attained — I shall declare to you in brief; 'saṅgraha' means brevity — by that brevity.
