When you chant harinama, you can try and visualize that you are anywhere in the eighty-four krosas (thirty-two square mile area) of Vrndavana. You can be under the shade of Vamsi-vata (the tree under which Krsna plays His flute and calls the gopis to come and dance rasa-lila with Him), and sometimes in Nandagaon, at Ter-kadamba (one of the important meeting places of Sri Radha-Krsna). And, if you like to weep bitterly, then go to Uddhava-kyari, where all gopis are lamenting in a mood of separation from Krsna. Sit there for some time and chant Hare Krsna, feeling something of the gopis’ great separation mood.
If your mind is wandering, go then to Govardhana and try to chant Hare Krsna loudly, performing parikrama of Govardhana. You can take some rest at Kusuma-sarovara (where Krsna jokingly chastises Sri Radha for picking ‘His’ flowers) or Govinda-kunda (where King Indra worshipped Krsna), and especially take bath at Radha-kunda. First take bath in Radha-kunda and then in Syama-kunda (where Radha and Krsna and the gopis perform their water sports).
While chanting Hare Krsna and thinking about all of these things, gradually your mind will be controlled. In our sampradaya, especially in the line of Srila Rupa Gosvami, devotees do not have to do anything separate to remove anarthas (detrimental thoughts and habits). We simply engage our minds all the time, second by second, in chanting, remembering, reading, and worshipping Krsna twenty-four hours a day. In this way our minds cannot go here and there, and we can conquer anarthas easily. We have a taste in these processes that assist us in entering bhakti.
