KAIVALYA UPANISHAD · 1

ॐ अथाश्वलायनो भगवन्तं परमेष्ठिनमुपसमेत्योवाच ।
अधीहि भगवन्ब्रह्मविद्यां वरिष्ठां सदा सद्भिः सेव्यमानां निगूढाम् ।
यथाचिरात्सर्वपापं व्यपोह्य परात्परं पुरुषं याति विद्वान् ॥ १॥

oṃ athāśvalāyano bhagavantaṃ parameṣṭhinamupasametyovāca ।
adhīhi bhagavanbrahmavidyāṃ variṣṭhāṃ sadā sadbhiḥ sevyamānāṃ nigūḍhām ।
yathācirātsarvapāpaṃ vyapohya parātparaṃ puruṣaṃ yāti vidvān ॥ 1॥

OM. Aswalayana to the Lord Parameshthi came and said, Teach me, Lord, the highest knowledge of Brahman, the secret knowledge ever followed by the saints, how the wise man swiftly putting from him all evil goeth to the Purusha who is higher than the highest.
