gokule kṛṣṇacandrasya sarvāpacchānti pūrvakam
dhīra-lālitya vṛddhy-arthaṁ kriyamāṇa vratādikā (22)
guru go vipra satkāra ratā vinaya sannatā
tad āśīḥ śata vardhiṣṇu saubhāgyādi guṇāṣcitā (23)

In Gokula She protects Kṛṣṇa-candra from all calamities and She takes different vows to increase Kṛṣṇa’s playful loveliness. She is always devoted to Her superiors, the cows and the brāhmaṇas, and She humbly bows down to them. Their resultant hundreds of blessings increase Her attributes like Her good fortune.

Stavāmṛta Kaṇā Vyākhyā:

Śrīmatī is always worried about all the demons that may attack Kṛṣṇa in Gokula, and therefore She takes vows for His protection and for the increase of His dhīra lālitya (playful loveliness).

Parama Vinītā (most humble) Śrī Rādhā is engaged in the service of the cows and the brāhmaṇas, and through Her extraordinary expertise in service She gains hundreds and thousands of blessings from them, and this increases Her attributes like Her good fortune.
Although all the divine attributes are naturally present in Kṛṣṇa premamayī Śrī Rādhārāṇī, still, for the sake of maintaining the sweetness of the human pastimes,
all the Vrajavāsīs think that She is so qualified and fortunate because of the blessings bestowed upon Her by Her superiors, the cows and the brāhmaṇas.
