MUṆḌAKA UPANISHAD · 3.2.5

संप्राप्यैनमृषयो ज्ञानतृप्ताः
कृतात्मानो वीतरागाः प्रशान्ताः ।
ते सर्वगं सर्वतः प्राप्य धीरा
युक्तात्मानः सर्वमेवाविशन्ति ॥ ५॥

saṃprāpyainamṛṣayo jñānatṛptāḥ
kṛtātmāno vītarāgāḥ praśāntāḥ ।
te sarvagaṃ sarvataḥ prāpya dhīrā
yuktātmānaḥ sarvamevāviśanti ॥ 5॥

Attaining to him, seers glad with fullness of knowledge, perfected in the Self, all passions cast from them, tranquillised, — these, the wise, come to the all-pervading from every side, and, uniting themselves with him, enter utterly the All.

Sri Aurobindo · CWSA 18, p. 145
