Dedicate your life for Krishna. That is the perfection. Even if there are some faults, dedicated life is noble life. Maybe, due to our past habits, we may commit some faulty action, but that dedicated life is sublime.- His Divine Grace A. C. Bhaktivedanta Swami Prabhupada Morning Walk, March 4, 1974 Mayapur, India

Vaidha bhaktas [practicing devotees] should always try to bring their hearts to the lotus feet of Krishna while spending their lives situated in varnanrama-dharma. This is bhakti-yoga.

In this age I will distribute devotional service that is desired by the demigods, sages, and perfected beings to everyone, including the untouchables, miscreants, Yavanas, dogeaters, women, nudras, and other fallen souls belonging to the lower castes. But people who are intoxicated by education, wealth, high birth, knowledge, and austerity, and who as a result commit offenses at the feet of My devotees, will be cheated in this age, for they will not accept My glories.- Sri Caitanya Mahaprabhu Sri Caitanya-bhagavata, Antya-khanna, 4.122–125

The essence of sadhana bhakti is to carefully consider and follow the path displayed by the previous and the present mahajanas (great personalities).
