The main tool to change the mind is constant and same intensity Smaran of Prabhu with love and devotion. Naam-Smaran of Bhagwan is the best tool to nudge the mind out of its habits. Whatever mind thinks, it is best to mix Naam-Smaran with sincerity of mind and heart to change the result of this thinking. When this happens, it is for sure that the force of the thoughts, its effect and impressions (Sanskaras) will be less. It is like, when something is added to poison that dilutes its effect, it is possible that there may not be the same bad results. Similarly, if we continue to do Naam-Smaran of Bhagwan with understanding and Bhavna in all the activities of the mind, we can be free from the clutches of the Sansar (worldly activities).
Second tool is the practice with determination, to keep alive the Bhavna and Dharna (mental thought) of Shree Bhagwan in all the daily activities.
Third tool is to continue to develop good qualities (Gunas) like Samata, peace, patience, equanimity, compassion for others etc., in our lives. If we have developed sincere Bhavna to make the Bhavna of developing our lives, we develop the understanding from experiences that whatever happens is for our own good. For this reason, every Sadhak will need to do at least this much to be free from all kind of clutches of the mind.
By the grace of Prabhu, if we can keep the mind in Bhava, there is nothing that will disturb the mind. It is my own experience that mind cannot be controlled completely by following certain rules and good behavior. So instead of trying to restrain and control the mind, we can take refuge in the higher energy than mind with Bhava of love, devotion and knowledge. We can transform mind, Prana etc., in its proper form easily with the help of intense prayers and Blessings-help-energy of Bhagwan.
