This is a revision for those who are already on this path and beginning for those who are new to this.
Follow ABCD to progress in Krishna Consciousness then anarthas will automatically go away.
A. Association with devotees (Temple as well as Congregation), and learn Vaisnava Etiquettes.
B. Book reading and book hearing. (Books by Srila Prabhupada) This will help to understand philosophy.
C. Chanting 16 rounds of Hare Krishna Mahamantra daily as well as discussions with senior devotees about Krishna Consciousness. It will definitely help you. You don't have to get sentimentally or emotionally involved in chanting. The need has to be understood philosophically and greed developed then only you can fix up your mind that it is the most essential part of your life.
D. Devotional service to Krishna & Spiritual Diet (Krishna Prasadam).
All above is devotional service. Cook Satwik food and offer to Krishna and eat prasadam after offering. Food should be without onion garlic, no tea, no coffee, no mushrooms, no vinegar, no non-veg stuff. It makes spiritual diet.
