naradas tad upakarnya

jnatva tasya cikirsitam

sprstva murdhany agha-ghnena

panina praha vismitah

 

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

The great sage Narada overheard this news, and understanding all the activities of Dhruva Maharaja, he was struck with wonder. He approached Dhruva, and touching the boy’s head with his all-virtuous hand, he spoke as follows.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

When Dhruva Maharaja was talking with his mother, Suniti, of all the incidents that had taken place in the palace, Narada was not present. Thus the question may be raised how Narada overheard all these topics. The answer is that Narada is trikala-jna; he is so powerful that he can understand the past, future and present of everyone’s heart, just like the Supersoul, the Supreme Personality of Godhead. Therefore, after understanding the strong determination of Dhruva Maharaja, Narada came to help him. It may be explained in this way: The Supreme Personality of Godhead is present in everyone’s heart, and as soon as He understands that a living entity is serious about entering devotional service, He sends His representative. In this way Narada was sent to Dhruva Maharaja. This is explained in the Caitanya-caritamrta. Guru-krsna-prasade paya bhakti-lata-bija: by the grace of the spiritual master and Krsna, one can enter into devotional service. Because of Dhruva Maharaja’s determination, Krsna, the Supersoul, immediately sent His representative, Narada, to initiate him.
