ŚVETĀŚVATARA UPANISHAD · 6.19
निष्कलं निष्क्रियं शान्तं निरवद्यं निरञ्जनम् ।
अमृतस्य परं सेतुं दग्धेन्धनम् इवानलम् ॥
niṣkalaṃ niṣkriyaṃ śāntaṃ niravadyaṃ nirañjanam ।
amṛtasya paraṃ setuṃ dagdhendhanam ivānalam ॥
Who is without parts, without actions, tranquil, without fault, without taint, the highest bridge to immortality--like a fire that has consumed its fuel.
F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
