Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Having summarized the teachings of Jada Bharata, Sukadeva Gosvami said: My dear King Pariksit, the path indicated by Jada Bharata is like the path followed by Garuda, the carrier of the Lord, and ordinary kings are just like flies. Flies cannot follow the path of Garuda, and to date none of the great kings and victorious leaders could follow this path of devotional service, not even mentally.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As Krsna says in Bhagavad-gita (7.3):
manusyanam sahasresu
kascid yatati siddhaye
yatatam api siddhanam
kascin mam vetti tattvatah
“Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth.” The path of devotional service is very difficult, even for great kings who have conquered many enemies. Although these kings were victorious on the battlefield, they could not conquer the bodily conception. There are many big leaders, yogis, svamis and so-called incarnations who are very much addicted to mental speculation and who advertise themselves as perfect personalities, but they are not ultimately successful. The path of devotional service is undoubtedly very difficult to follow, but it becomes very easy if the candidate actually wants to follow the path of the mahajana. In this age there is the path of Sri Caitanya Mahaprabhu, who appeared to deliver all fallen souls. This path is so simple and easy that everyone can take to it by chanting the holy name of the Lord.
harer nama harer nama
harer namaiva kevalam
kalau nasty eva nasty eva
nasty eva gatir anyatha
We are very satisfied that this path is being opened by this Krsna consciousness movement because so many European and American boys and girls are taking this philosophy seriously and gradually attaining perfection.
