ŚVETĀŚVATARA UPANISHAD · 6.21

तपःप्रभावाद् देवप्रसादात् ब्रह्म ह श्वेताश्वतरो ऽथ विद्वान् ।
अत्याश्रमिभ्यः परमं पवित्रं प्रोवाच सम्यग् ऋषिसङ्घजुष्टम् ॥

tapaḥprabhāvād devaprasādāt brahma ha śvetāśvataro ’tha vidvān ।
atyāśramibhyaḥ paramaṃ pavitraṃ provāca samyag ṛṣisaṅghajuṣṭam ॥

Through the power of his penance and through the grace of God has the wise Svetâsvatara truly proclaimed Brahman, the highest and holiest, to the best of ascetics, as approved by the company of Rishis.
