The Vaiṣṇava becomes the ocean of mercy to others. They're going door to door: "Please be Kṛṣṇa conscious. You'll be happy." Actually that is the fact. So who can be merciful than these Vaiṣṇavas? They are giving the right contribution to the society. They need it.
So simply by God consciousness, simply by Kṛṣṇa consciousness, we can develop all the good qualities, we can conquer over all reactions of our sinful life. Simply we have to follow the regulative principles as they're enjoined by the ācāryas, as they're... Very simple method. And by chanting this Hare Kṛṣṇa mantra, as much as possible, then we keep the standard. We keep the standard means we keep ourself in liberated state. Simply we have to be cautious that māyā, or material conception of life, may not again attack us. So (he) says, na tathā hy aghavān rājan pūyeta tapa-ādibhiḥ, yathā kṛṣṇārpita-prāṇaḥ. Anyone who has dedicated himself, his life, to Kṛṣṇa, na ta..., yathā kṛṣṇārpita-prāṇas tat-puruṣa-niṣevayā... How one can become dedicated to Kṛṣṇa? Tat-puruṣa-niṣevayā. That Supreme Personality being served, being served. By serving. You can, you can, simply by lip... But you cannot say that "Now I have dedicated my life to Kṛṣṇa." No. That's all right, but you have to keep the standard of surrender by niṣevayā, by serving. Sevonmukhe hi jihvādau svayam eva (Brs. 1.2.234). As you serve, as you go on serving the Supreme Lord, so He becomes revealed within your... He's within your heart. So by your service He'll reveal Himself. So kṛṣṇārpita-prāṇas tat-puruṣa-niṣevayā. We should remember this, that our business is that we should be dedicated to Kṛṣṇa. Our life, everything, should be dedicated to Kṛṣṇa. And how it can be possible? Tat-puruṣa-niṣevayā. Simply by serving the Supreme Personality.
So this program, this devotional service, morning, from morning till night, is simply how to serve Him. The more we serve, then we become dedicated to Kṛṣṇa. And Kṛṣṇa says on the Bhagavad-gītā the same thing: teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10). Persons who are twenty-four hours engaged, satata-yuktānām... Satata means twenty-four hours. Not that five minutes or fifteen minutes meditation, and then do all nonsense. No. Twenty-four hours one should be engaged in the service of the Lord. Twenty-four hours. That we are doing. Whatever he knows, whatever talent he has got, use for Kṛṣṇa. That is twenty-four hours' engagement.
