"O great sage, out of many millions of liberated persons and persons who have achieved success in mystic yoga, one who is completely devoted to the Supreme Personality of Godhead and who is filled with peace is very hard to find." (SB 6.14.5)
In this way Lord Caitanya explained that of the many thousands and millions of living entities wandering in the material world, one who by the grace of Lord Kṛṣṇa and the spiritual master gets the seed of devotional service is very rare and fortunate. A pious or religious man is generally inclined to worship deities in various temples, but if by chance, even without his knowledge, he offers his obeisances to Lord Viṣṇu or receives the favor of a Vaiṣṇava, a devotee of the Lord, he at that time acquires the asset necessary to approach the Supreme Personality of Godhead. This is clearly understood from the life story of the great sage Nārada, which is related in Śrīmad-Bhāgavatam.
