If one comes into contact with Krishna Consciousness and executes the process under the guidance of a bona fide guide, he is sure to go back to Godhead.
The spiritual master's order should be taken as the prime duty of life. If one gets a bona fide spiritual master and acts according to his direction, then his perfection of life in Krishna Consciousness is guaranteed.
The cultivation of Krishna Consciousness is possible where great devotees live together and constantly engage in hearing and chanting the glories of the Lord.
How to make Krishna Consciousness interesting? How to make it attractive and relevant for everyone is what Prahlad Maharaj is showing us, "Look! don't waste your life!" Ultimately if we don't realize who we are and who is Krishna? What is the use of this human form of life?
Krishna Conciousness has two main elements – Restraining the sense from sense gratification (four regulative principles) and fixing mind on Krishna (Chanting – Remembring Krishna all the time and NOT FORGETTING KRISHNA any moment at the same time).
This human form of life is a chance to be trained to be agreeable to the orders of the Supreme Lord. To bring about this training in society is the mission of the Krishna consciousness movement.
