KAIVALYA UPANISHAD · 3–4

न कर्मणा न प्रजया धनेन त्यागेनैके अमृतत्वमानशुः ।
परेण नाकं निहितं गुहायां विभ्राजते यद्यतयो विशन्ति ॥ ३॥

वेदान्तविज्ञानसुनिश्चितार्थाः संन्यासयोगाद्यतयः शुद्धसत्त्वाः ।
ते ब्रह्मलोकेषु परान्तकाले परामृताः परिमुच्यन्ति सर्वे ॥ ४॥

na karmaṇā na prajayā dhanena tyāgenaike amṛtatvamānaśuḥ ।
pareṇa nākaṃ nihitaṃ guhāyāṃ vibhrājate yadyatayo viśanti ॥ 3॥

vedāntavijñānasuniścitārthāḥ saṃnyāsayogādyatayaḥ śuddhasattvāḥ ।
te brahmalokeṣu parāntakāle parāmṛtāḥ parimucyanti sarve ॥ 4॥

Persons attain salvation not through Karma, progeny or wealth but through Sannyāsa (renunciation) alone. Ascetics of pure mind through (the realisation of) the meaning well-ascertained by Vedānta-Vijñāna and through Śannyāsa-Yoga enter into That which is above Swarga (heaven) and is in the cave (of the heart). They all attain Paramātmā in the Brahma-world and are (finally) emancipated.
