I am 100% convinced that without devotee association we don't stand a chance against the onslaughts of the material energy. As difficult as it may seem at times, we must always situate ourselves in such a way that we can favorably associate with devotees by continually hearing and chanting the glories of Krishna and His pure devotee, Srila Prabhupada. If that continues then automatically service will be there, and advancement is guaranteed.
