Question: Is it possible in Krishna Consciousness to cross all the stages of anartha nivritti in one life time and become a pure devotee? Can our efforts, along with Krishna’s mercy, help us achieve pure transcendental love of Krishna in this life time itself?
Answer by Romapada Swami :
Yes, most definitely, Srila Prabhupada assured us, that it is possible to achieve pure loving devotion to Krishna in this very life time. The deciding factors are, as you have mentioned in your question, the intensity of our efforts taken up under proper guidance and in a mood of submission to Guru and Krishna, combined with the mercy of Krishna.
Pure devotional service, like the intense rays of the sun, when performed with singular focus and attention in the matter of hearing, chanting, worshiping and serving devotees, can very quickly uproot all anarthas (unwanted things in the heart) and bring us to the stage of pure devotion. (Cf SB 1.2.14, 18, 19, 20, and 21)
