ŚVETĀŚVATARA UPANISHAD · 2.6
अग्निर् यत्राभिमथ्यते वायुर् यत्राधिरुध्यते ।
सोमो यत्रातिरिच्यते तत्र संजायते मनः ॥
agnir yatrābhimathyate vāyur yatrādhirudhyate ।
somo yatrātiricyate tatra saṃjāyate manaḥ ॥
Where the fire is rubbed, where the wind is checked, where the Soma flows over, there the mind is born.
F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
