Radhanath Swami: It is the not the nature of the mind to pursue selfishness and egoism and thus experience frustration and depression in due course of time. It is the nature of the mind to pursue the needs of the soul and thus find peace, compassion, happiness and ecstatic enlightenment. It is the actual nature of the mind to always be filled with transcendental pleasure. This happens when it is connected to the will of the atma, the eternal soul. But when we forget our real nature and pursue the desires of the false ego—under the misconception that I am this mind, I am this body, I am the controller, the proprietor and the enjoyer—it is the nature of the mind to be implicated in material bondage and suffering in that condition.
If we want to free our mind, the easiest way is to chant mantra. The word mantra means to deliver the mind from its artificial conditions and to bring it back to its original, natural, pure state. It is for this reason that the greatest welfare work is to teach people how to purify and cleanse their heart through chanting God’s names, Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama Hare Rama Rama Rama Hare Hare.
