Kṛṣṇa-bhaktas are free from all material desires. Although those who are theoretically liberated by knowing that the living entity is not material may be classified among liberated souls, they still have desires. Their main desire is to become one with the Supreme Personality of Godhead. Such persons are very much attached to performing Vedic rituals and righteous activities in order to enjoy material prosperity. Even when some of them transcend material enjoyment, they still try to enjoy in the spiritual world by merging into the existence of the Supreme Lord. Some of them also desire to attain mystic powers through the execution of yoga. As long as any of these desires are within a person's heart, he cannot understand the nature of pure devotional service, and on account of constantly being agitated by such desires, he is not peaceful. Indeed, as long as there is any desire for material perfection at all, one cannot be at peace. Since the devotees of Lord Kṛṣṇa do not desire anything material, they are the only peaceful persons within this material world. This is confirmed in Śrīmad-Bhāgavatam (6.14.5):
- muktānām api siddhānāṁ nārāyaṇa-parāyaṇaḥ
- su-durlabhaḥ praśāntātmā koṭiṣv api mahāmune
"O great sage, out of many millions of liberated persons and persons who have achieved success in mystic yoga, it is very rare to find one who is completely devoted to the Supreme Personality of Godhead and is therefore filled with peace."
Lord Caitanya next 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 and worshipful respects to Lord Viṣṇu and receives the favor of a Vaiṣṇava, a devotee of the Lord, at that time he acquires the asset necessary to approach the Supreme Personality of Godhead. This is plainly understood from the history of the great sage Nārada, which is related in Śrīmad-Bhāgavatam. By serving Vaiṣṇavas in his previous life, Nārada was favored by those devotees of the Lord and became the great sage Nārada Muni.
Vaiṣṇavas are generally very compassionate toward the conditioned souls. Without even being invited, a devotee will go from door to door to enlighten people, to bring them out of the darkness of nescience by imparting knowledge of the living entity's constitutional position as a servant of Lord Kṛṣṇa. Such devotees are empowered by the Lord to distribute devotional consciousness, or Kṛṣṇa consciousness, to the people in general. They are known as authorized spiritual masters, and it is by the mercy of such a spiritual master that a conditioned soul gets the seed of devotional service. The causeless mercy of the Supreme Personality of Godhead is first appreciated when one comes in touch with a bona fide spiritual master, who can enlighten the conditioned soul and bring him to the highest position of devotional life. Therefore Lord Caitanya said that by the mercy of the spiritual master one can achieve the causeless mercy of the Lord and by the mercy of the Supreme Personality of Godhead one can attain the mercy of the bona fide spiritual master.
