evam - in this manner; māsam - an entire month; vratam - their vow; ceruḥ - they executed; kumāryaḥ - the girls; kṛṣṇa-cetasaḥ - their minds absorbed in Kṛṣṇa; bhadra-kālīm - the goddess Kātyāyanī; samānarcuḥ - they properly worshiped; bhūyāt - may He become; nanda-sutaḥ - the son of King Nanda; patiḥ - my husband.

Thus for an entire month the girls carried out their vow and properly worshiped the goddess Bhadrakālī, fully absorbing their minds in Kṛṣṇa and meditating upon the following thought: “May the son of King Nanda become my husband.”
