Swamiji: First increase the love and devotion for God. Just like during Ramayan recitation, if you engage your mind and with concentration and understanding the meaning, then mind is greatly purified. Attachment within is wiped out on it's own and devotion for God is awakened. There is amazing joy and relish in this. In the beginning sometimes a man may feel bored, but when he starts getting deeply into it and experiences the nectar, he is no longer uninterested. See for yourself. Also, read the lives of devotees and saints that have freed themselves from the bondage of the world. There is immense gain in this as such readings penetrate the heart. And when love is awakened within, then attachment and worldly desires will naturally drop off. You will be greatly benefited. Attachment can also be removed through knowledge and inquiry, but love works wonders.
