only possible by serving a pure devotee

 
he stage of pure devotion is attained by sincerely serving a pure devotee of the Lord. The first condition of devotional service to the Lord is therefore to be a servant of a pure devotee,
According to Srila Visvanatha Cakravarti Thakur, the breathing dead body is a ghost. When a man dies, he is called dead, but when he again appears in a subtle form not visible to the present vision and yet acts, such a dead body is called a ghost. Ghosts are always very bad elements, always creating a fearful situation for others. Similarly, the ghost-like nondevotees who have no respect for the pure devotees, nor for the Visnu Deity in the temples, create a fearful situation for the devotees at all times. The Lord never accepts any offering by such impure ghosts. There is a common saying that one should first love the dog of the beloved before one shows any loving sentiments for the beloved. The stage of a pure devotee is attained by sincerely serving a pure devotee of the Lord. The first condition of devotional service of the Lord is therefore to be a servant of a pure devotee, and this condition is fulfilled by the statement "reception of the dust of the lotus feet of a pure devotee who also served another pure devotee." That is the way of pure disciplic succession, or devotional parampara.    (More...)
"O King Rahūgana, the perfectional stage of devotional service or the paramahamsa stage of life cannot be attained without being blessed by the dust of the feet of great devotees. It is never attained by tapasya (austerity), the Vedic worshiping process, acceptance of renounced order of life, the discharge of the duties of household life, the chanting of the Vedic hymns, or the performance of penances in the hot sun, within cold water or before the blazing fire."    (More...)
In other words, Lord Sri Krsna is the property of His pure unconditional devotees, and as such only the devotees can deliver Krsna to another devotee; Krsna is never obtainable directly. Lord Caitanya therefore designated Himself as the "gopi-bhartur dasa-dasa dasanudasa," or "the most obedient servant of the servants of the Lord who maintains the gopi damsels at Vrndavana." A pure devotee therefore never approaches the Lord directly, but tries to please the Lord's servant of servants, and thus the Lord becomes pleased, and the devotee then only can relish the taste of the tulasi leaves stuck to His lotus feet. In the Brahma-samhita it is said that the Lord is never to be found by becoming a great scholar of the Vedic literatures, but He is very easily approachable through His pure devotee. In Vrndavana all the pure devotees pray for the mercy of Srimati Radharani, the pleasure potency of Lord Krsna. Srimati Radharani is a tender-hearted feminine counterpart of the supreme whole, resembling the perfectional stage of the worldly feminine nature. Therefore, the mercy of Radharani is available very readily by the sincere devotees, and once She recommends such a devotee to Lord Krsna, the Lord at once accepts the devotee's admittance in His association. The conclusion is, therefore, that one should be more serious about seeking the mercy of the devotee than that of the Lord directly, and by doing so (by the good will of the devotee) the natural attraction for the service of the Lord will be revived.    (More...)
"Both by rising and setting, the sun decreases the duration of life of everyone, except one who utilizes the time by discussing topics of the all-good Personality of Godhead. Do the trees not live? Do the bellows of the blacksmith not breathe? All around us, do the beasts not eat and discharge semen? Men who are like dogs, hogs, camels and asses praise those men who never listen to the transcendental pastimes of Lord Sri Krsna, the deliverer from evils. One who has not listened to the messages about the prowess and marvelous acts of the Personality of Godhead and has not sung or chanted loudly the worthy songs about the Lord should be considered to possess ears like the holes of snakes and a tongue like that of a frog. The upper portion of the body, though crowned with a silk turban, is only a heavy burden if not bowed down before the Personality of Godhead, who can award mukti [freedom]. And the hands, though decorated with glittering bangles, are like those of a dead man if not engaged in the service of the Personality of Godhead Hari. The eyes which do not look at the symbolic representations of the Personality of Godhead Visnu [His forms, name, quality, etc.] are like those printed on the plumes of a peacock, and the legs which do not move to the holy places [where the Lord is remembered] are considered to be like tree trunks. The person who has not at any time received upon his head the dust from the feet of a pure devotee of the Lord is certainly a dead body. And the person who has never experienced the flavor of the tulasi leaves from the lotus feet of the Lord is also a dead body, although breathing. Certainly that heart is steel-framed which, in spite of one's chanting the holy name of the Lord with concentration, does not change when ecstasy takes place, tears fill the eyes and the hairs stand on end."    (More...)
"Maharaja Rahūgana inquired from the great saint Jaḍa Bharata as to how he attained such a liberated stage of a paramahamsa, and in answer the great saint replied as follows:    (More...)
