Chapter 64: Viśvāmitra Falls Prey to Anger
Text 1.64.13

यन्मां लोभयसे रम्भे कामक्रोधजयैषिणम्।
दश वर्षसहस्राणि शैली स्थास्यसि दुर्भगे॥

yan māṁ lobhayase rambhe kāma-krodha-jayaiṣiṇam
daśa
varṣa-sahasrāṇi śailī sthāsyasi durbhage

yat = because; mām = me; lobhayase = you allured; rambhe = O Rambhā; kāma-krodha-jaya-eṣiṇam = who desired to conquer lust and anger; daśa varṣa-sahasrāṇi = for 10,000 years; śailī sthāsyasi = you will be a stone; durbhage = O evil endeavorer.[1]

O Rambhā, O evil endeavorer, because you allured me who desired to conquer lust and anger, you will be a stone for 10,000 years.

Śailī indicates that Rambhā would become a stone statue.
