SB Canto 10.1 to 10.13

The Vedas (Śvetāśvatara Upaniṣad 6.8) assert that the Supreme Personality of Godhead has nothing to do personally (na tasya kāryaṁ karaṇaṁ ca vidyate) because He is doing everything through His energies and potencies (parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport)). Nonetheless, here we see that He took personal care to find the calves of His friends. This was Kṛṣṇa's causeless mercy.

SB 10.13.14, Translation and Purport

"Let Me go and search for the calves," Kṛṣṇa said. "Don't disturb your enjoyment." Then, carrying His yogurt and rice in His hand, the Supreme Personality of Godhead, Kṛṣṇa, immediately went out to search for the calves of His friends. To please His friends, He began searching in all the mountains, mountain caves, bushes and narrow passages.

The Vedas (Śvetāśvatara Upaniṣad 6.8) assert that the Supreme Personality of Godhead has nothing to do personally (na tasya kāryaṁ karaṇaṁ ca vidyate) because He is doing everything through His energies and potencies (parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport)). Nonetheless, here we see that He took personal care to find the calves of His friends. This was Kṛṣṇa's causeless mercy. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: (BG 9.10) all the affairs of the entire world and the entire cosmic manifestation are working under His direction, through His different energies. Still, when there is a need to take care of His friends, He does this personally. Kṛṣṇa assured His friends, "Don't be afraid. I am going personally to search for your calves." This was Kṛṣṇa's causeless mercy.
