How to purify the mind

The easiest way to purify the mind is to chant. To chant continuously the name of God. You were chanting the Maha Mantra: “Hare Ram Hare Ram, Ram Ram Hare Hare, Hare Krishna Hare Krishna, Krishna Krishna Hare Hare.” It is said that by just chanting this mantra, one can get liberation. But one has to chant it with faith. Mere chanting alone will not help, but chanting with the heart, will help.
And how to chant with the heart? How to train the mind to calm itself? By forcing it. When you discipline yourself and say, "Okay, today I will chant,” then you start by taking your japa mala or rosary, and you chant your mantra so you are focusing yourself on it, you are dragging the mind and putting your focus on the mantra. The more you do it, the more you will see that with time you will not even need the japa mala. You will not need any rosary because the mantra will automatically be chanted inside your heart.
