तस्यास्तद्वचनं श्रुत्वा विस्मिता मन्दविस्मया।
कृतमित्यब्रवीत्सीता तपोबलसमन्विताम्॥
tasyās tad vacanaṁ śrutvā vismitā manda-vismayā
kṛtam ity abravīt sītā tapo-bala-samanvitām
tasyāḥ tat = those; vacanam = words; śrutvā = upon hearing; vismitā = was surprised; manda-vismayā = with a gentle smile; kṛtam iti = you have already done everything for me; abravīt = she told Anasūyā; sītā = Sītā-devī; tapaḥ-bala-samanvitām = who was endowed with the strength of asceticism.
Upon hearing those words, Sītā-devī was suprised. With a gentle smile, she told Anasūyā who was endowed with the strength of asceticism, “You have already done everything for me.”1
