Ramayana
प्रत्ययार्थं ततः सीता विवेश ज्वलनं तदा । प्रत्यक्षं तव सौमित्रे देवानां हव्यवाहनः । अपापां मैथिलीमाह वायुश्चाकाशगोचरः ॥ 7-45-7 ॥
"Then, for the sake of proof, Sita entered the fire at that time—before your very eyes, Saumitri—and the bearer of the gods' oblations declared Maithili to be without sin, and so too did the Wind that ranges through the sky."
