I see you, you see me. I touch you, you touch me. I taste something. This is gross. Above this gross there is mental platform. So mantra is also on the mental, which is little above intelligence and above that there is spiritual platform. So if on the mental platform, the mantra can act so wonderfully, how much spiritually the mantra can benefit you. You have to simply imagine. So this Hare Krishna mantra is completely spiritual. If you chant it, spiritually enlightened, then surely it will act.

Even by fighting, you can be a great devotee, just like Arjuna. He was not chanting on the beads, but he was fighting. But still, bhakto ‘si priyo ‘si me [Bg. 4.3]. Krishna says, “Oh, you are My great devotee.” Now people, may say that “He was not chanting. He was fighting. How he became a great devotee?” But Krishna says, bhakto ‘si priyo ‘si me: “You are My dear friend. You are My devotee. Because you are utilizing your energy for Me.” So bhakti means you utilize your energy for Krishna. Then your life is perfect.

A devotee is not afraid of going to hell if he has the opportunity to hear the glories of the Lord constantly. This is the advantage of chanting Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. One may be put in any condition, but God gives him the prerogative to chant Hare Krishna. In any condition of life, if one goes on chanting he will never be unhappy.
