SB 10.11.57
aho brahma-vidam vaco
nasatyah santi karhicit
gargo yad aha bhagavan
anvabhavi tathaiva tat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The words of persons in full knowledge of Brahman never become untrue. It is very wonderful that whatever Garga Muni predicted we are now actually experiencing in all detail.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The purpose of human life is indicated in the Brahma-sutra: athato brahma jijñasa. To make one’s life perfect in the past, present and future one must learn about Brahman. Because of intense affection, Nanda Maharaja could not understand Krsna as He is. Garga Muni was able to know everything, past, present and future, by studying the Vedas, but Nanda Maharaja could not understand Krsna directly. Because of his intense love for Krsna, he forgot who Krsna was and could not understand Krsna’s potency. Although Krsna is Narayana Himself, Garga Muni did not disclose this. Thus Nanda Maharaja appreciated the words of Garga Muni, but because of his deep affection he could not understand who Krsna was, although Garga Muni had said that Krsna’s qualities would be exactly like those of Narayana.
