MUṆḌAKA UPANISHAD · 3.2.6

वेदान्तविज्ञानसुनिश्चितार्थाः
संन्यासयोगाद्यतयः शुद्धसत्त्वाः ।
ते ब्रह्मलोकेषु परान्तकाले
परामृताः परिमुच्यन्ति सर्वे ॥ ६॥

vedāntavijñānasuniścitārthāḥ
saṃnyāsayogādyatayaḥ śuddhasattvāḥ ।
te brahmalokeṣu parāntakāle
parāmṛtāḥ parimucyanti sarve ॥ 6॥

Doers of askesis who have made sure of the aim of the whole-knowledge of Vedanta, the inner being purified by the Yoga of renunciation, all in the hour of their last end passing beyond death are released into the worlds of the Brahman.

Sri Aurobindo · CWSA 18, p. 145
