Sanskrit:

उलूखलाङ्‌घ्रेरुपरि व्यवस्थितंमर्काय कामं ददतं शिचि स्थितम् ।हैयङ्गवं चौर्यविशङ्कितेक्षणंनिरीक्ष्य पश्चात् सुतमागमच्छनै: ॥ ८ ॥

ITRANS:

ulūkhalāṅghrer upari vyavasthitaṁmarkāya kāmaṁ dadataṁ śici sthitamhaiyaṅgavaṁ caurya-viśaṅkitekṣaṇaṁnirīkṣya paścāt sutam āgamac chanaiḥ

Translation:

Kṛṣṇa, at that time, was sitting on an upside-down wooden mortar for grinding spices and was distributing milk preparations such as yogurt and butter to the monkeys as He liked. Because of having stolen, He was looking all around with great anxiety, suspecting that He might be chastised by His mother. Mother Yaśodā, upon seeing Him, very cautiously approached Him from behind.

Purport:

Mother Yaśodā was able to trace Kṛṣṇa by following His butter-smeared footprints. She saw that Kṛṣṇa was stealing butter, and thus she smiled. Meanwhile, the crows also entered the room and came out in fear. Thus mother Yaśodā found Kṛṣṇa stealing butter and very anxiously looking here and there.
