Somehow or other you have to engage your mind at the lotus feet of Krsna. Therefore so many paraphernalia how to engage your mind. Sravanam kirtanam visnoh: hearing about Krsna, chanting about Krsna, thinking of Krsna, worshiping Krsna, talking about Krsna, writing about Krsna, selling the books about Krsna, eating Krsna prasadam. In this way you become Krsna-ized. All-around Krsna. That is Krsna consciousness. This is called bhakti-yoga. This is called bhakti. Somehow or other, you become surrounded by Krsna atmosphere. This is Krsna consciousness.
