If you come back to Kṛṣṇa, wherefrom you generated, then you become eternally living, not to come back again in this material world full of miseries and frustration.
So these informations are there, and our propaganda is to train people how to become Kṛṣṇa conscious, how to understand Kṛṣṇa in truth so that next life, after giving up this body, you get your original, spiritual body, and you live forever with complete knowledge and blissful life. And to understand Kṛṣṇa, for this age it is very simple: this chanting process.
This chanting process—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—it is simple. Even a child can chant. We have got experience. When we hold meeting, unless one is very obstinate, he joins and chants Hare Kṛṣṇa mantra, and dances also with ecstasy. He doesn't require to understand what is Hare Kṛṣṇa mantra, but because it is spiritual vibration, it appeals to the spirit soul, and immediately he become ecstatic. That is the process.
So by chanting Hare Kṛṣṇa mantra, your heart, the mirror of your heart, becomes cleansed so that you can see. Just like mirror, when it is dusty, you cannot see your face nicely, similarly, when our heart is contaminated with the material infection, we cannot understand our real position. But if we chant this Hare Kṛṣṇa mantra, then it will be possible to understand, to see our constitutional position.
