srila prabhupada

Even if one wanders for many millions of years, from the time of creation until the time of annihilation, one cannot get free from the path of material existence unless one receives shelter at the lotus feet of a pure devotee."
                                                                                         ——————-(Srimad-Bhagavatam 5.14.41, Purport)
"The human form is an opportunity to take shelter of the bona fide spiritual master and, through him, the Supreme Lord. This Krishna consciousness movement has been started to give an opportunity to all the members of human society, who are misled by foolish leaders. No one can get out of this struggle for existence, which is full of miseries, without accepting a pure devotee of the Lord. The material attempt changes from one position to another, and no one actually gains relief from the struggle for existence. The only resort is the lotus feet of a bona fide spiritual master, and, through him, the lotus feet of the Lord."

"To save oneself, one must take shelter of a pure devotee. Narottama dasa Thakura therefore says, chadiya vaishnava-seva nistara payeche keba. If one wants to save himself from material nature's onslaughts, which arise because of the material body, one must become Krishna conscious and try to fully understand Krishna. As stated in Bhagavad-gita (BG 4.9), janma karma ca me divyam evam yo vetti tattvataha. One should understand Krishna in truth, and this one can do only by serving a pure devotee."
                                                                                        ———————-(Srimad-Bhagavatam 7.9.24, Purport)
"To take shelter of the lotus feet of the Lord means to take shelter of the pure devotees. The pure devotees whose only business is serving are honored by the names Prabhupada and Vishnupada, which indicate such devotees to be representatives of the lotus feet of the Lord. Anyone, therefore, who takes shelter of the lotus feet of a pure devotee by accepting the pure devotee as his spiritual master can be at once purified. Such devotees of the Lord are honored equally with the Lord because they are engaged in the most confidential service of the Lord, for they deliver out of the material world the fallen souls whom the Lord wants to return home, back to Godhead.
                                                                                        ———————-(Srimad-Bhagavatam 1.1.15, Purport)
"Everyone is eligible for the supreme destination. In the Srimad-Bhagavatam (SB 2.4.18) it is stated that even the lowest, who are called chandalas (dog-eaters), can be purified by association with a pure devotee. Therefore devotional service and the guidance of a pure devotee are so strong that there is no discrimination between the lower and higher classes of men; anyone can take to it. The most simple man taking shelter of the pure devotee can be purified by proper guidance."
