As Kṛṣṇa says in Bhagavad-gītā (7.3) :

manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye yatatām api siddhānāṁ kaścin māṁ vetti tattvataḥ

“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, yogīs, svāmīs 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 mahājana. In this age there is the path of Śrī Caitanya Mahāprabhu, 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 nāma harer nāma harer nāmaiva kevalam kalau nāsty eva nāsty eva nāsty eva gatir anyathā

We are very satisfied that this path is being opened by this Kṛṣṇa consciousness movement because so many European and American boys and girls are taking this philosophy seriously and gradually attaining perfection.
