क्षुत्तृड्भ्यामुदरं सिन्धुर्नोदतिष्ठत्तदा विराट् ।हृदयं मनसा चन्द्रो नोदतिष्ठत्तदा विराट् ॥ ६८ ॥
ITRANS:
kṣut-tṛḍbhyām udaraṁ sindhurnodatiṣṭhat tadā virāṭhṛdayaṁ manasā candronodatiṣṭhat tadā virāṭ
Translation:
The ocean entered His abdomen with hunger and thirst, but the Cosmic Being refused to rise even then. The moon-god entered His heart with the mind, but the Cosmic Being would not be roused.
