BṚHADĀRAṆYAKA UPANISHAD · 4.3.21

तद् वा अस्यैतद् अतिच्छन्दो ऽपहतपाप्माभयं रूपम् ।
तद् यथा प्रियया स्त्रिया संपरिष्वक्तो न बाह्यं किं चन वेद नान्तरम् ।
एवम् एवायं पुरुषः प्राज्ञेनात्मना संपरिष्वक्तो न बाह्यं किं चन वेद नान्तरम् ।
तद् वा अस्यैतद् आप्तकामम् आत्मकामम् अकामं रूपम् शोकान्तरम् ॥

tad vā asyaitad aticchando ’pahatapāpmābhayaṃ rūpam ।
tad yathā priyayā striyā saṃpariṣvakto na bāhyaṃ kiṃ cana veda nāntaram ।
evam evāyaṃ puruṣaḥ prājñenātmanā saṃpariṣvakto na bāhyaṃ kiṃ cana veda nāntaram ।
tad vā asyaitad āptakāmam ātmakāmam akāmaṃ rūpam śokāntaram ॥

'This indeed is his (true) form, free from desires, free from evil, free from fear. Now as a man, when embraced by a beloved wife, knows nothing that is without, nothing that is within, thus this person, when embraced by the intelligent (prâgña) Self, knows nothing that is without, nothing that is within. This indeed is his (true) form, in which his wishes are fulfilled, in which the Self (only) is his wish, in which no wish is left,--free from any sorrow.
