There are several, who, despite chanting the Lord’s name for several hours, days and months together, did not transform themselves even one bit. The demonic nature of Ravana, Bhasmasura and Kamsa did not diminish even a little, despite their chanting of the Lord’s name. What is the reason for this? All their sense organs function with the feeling: "I am the body (Aham Dehosmi)." Those who utter the name of the Lord while being immersed in body consciousness cannot realise the Divine, however long their penance may last. You are the embodiment of Divine Consciousness. Only when you are pure, you can experience that consciousness. Through attachment to worldly pleasures one gets bound to the physical and becomes oblivious to one’s essential Divinity.
