Devotion to Krishna naturally purifies the heart and generates true detachment far beyond what rituals accomplish.Listen — Srila Prabhupada Uvaca
Prabhupāda: yathā sujātayā bhaktyā śuddhyen nātmā vratādibhiḥ [SB 6.3.32] [One who constantly hears and chants the holy name of the Lord and hears and chants about His activities can very easily attain the platform of pure devotional service, which can cleanse the dirt from one's heart. One cannot achieve such purification merely by observing vows and performing Vedic ritualistic ceremonies.] People observe many religious ritualistic ceremonies known as yajña, vrata, dāna, tapaḥ, tapasya but here it is stated that simply by: śṛṇvatāṁ gṛṇatāṁ vīryāṇy uddāmāni harer muhuḥ [SB 6.3.32] If one simply becomes engaged in reciting and glorifying the transcendental pastimes and activities of the Supreme Personality of Godhead—muhuḥ, harer muhuḥ—twenty-four hours. Just like Caitanya Mahāprabhu said, kīrtanīyaḥ sadā hariḥ [Cc Antya 20.21], life should be so moulded that this kīrtana will go on twenty-four hours. [One who thinks himself lower than the grass, who is more tolerant than a tree, and who does not expect personal honor but is always prepared to give all respect to others can very easily always chant the holy name of the Lord.] Even you are engaged in your occupational duties if you practice it.
It will go on twenty-four hours and when you are advanced in practice as soon as you chant the Hare Kṛṣṇa mantra immediately the Kṛṣṇa with all His paraphernalia. Kṛṣṇa does not mean alone, just like when we speak, "The king is coming," that does not mean king is coming alone. He is coming, his private secretary is coming, his etikong [?] is coming, his military secretary is carrying on, so many people are coming. Similarly Kṛṣṇa those who are impersonalists, voidists, for them Kṛṣṇa has nothing to do.
But actually those who are devotees of Kṛṣṇa as soon as they chant this word, "Kṛṣṇa" or, "Rāma," immediately all Kṛṣṇa's paraphernalia becomes manifest. Just like it is stated in the Brahma-saṁhitā [Bs 5.29]: cintāmaṇi-prakara-sadmasu kalpa-vṛkṣalakṣāvṛteṣu surabhīr abhipālayantam lakṣmī-sahasra-śata-sambhrama-sevyamānaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi [I worship Govinda, the primeval Lord, the first progenitor who is tending the cows, yielding all desire, in abodes built with spiritual gems, surrounded by millions of purpose trees, always served with great reverence and affection by hundreds of thousands of lakṣmīs or gopīs.] Kṛṣṇa means Kṛṣṇa, immediately Kṛṣṇa's Vṛndāvana-līlā, Kṛṣṇa's Dvārakā-līlā, Kṛṣṇa's Mathurā-līlā, immediately becomes in rememberence. Kṛṣṇa who is fighting with such-and-such demons, Kṛṣṇa is playing with His cowherd boyfriends, Kṛṣṇa is dancing with the gopīs. Kṛṣṇa is speaking with His mother, Kṛṣṇa is joking with His friends, Kṛṣṇa is taking the cows to the pasturing grounds there He is taking bath in the...
So many things will come in your mind. So these descriptions are there in the Kṛṣṇa. So actually one who is advanced in Kṛṣṇa consciousness, simply by chanting one word, "Kṛṣṇa," so many things will come—harer muhuḥ: and this remembering of Kṛṣṇa's pastimes when you are accustomed. Then even when you are sleeping you will think of Kṛṣṇa—harer muhuḥ.
That is perfection of Kṛṣṇa consciousness. Not a second, not a moment he is without Kṛṣṇa consciousness. That is recommended here: śṛṇvatāṁ gṛṇatāṁ vīryāṇy uddāmāni, because when you are thinking of Kṛṣṇa everything is profoundly uddāmāni—encouraged. Kṛṣṇa is engaged in fighting with the demons, how He is saving his friends in the forest fire, everything is.
How He has lifted the Govardhan hill. All endeavors are uncommon in the human society, they are very interesting especially to the devotees. Yathā sujātayā bhaktyā: but these things happen when you are developed in devotional service—bhaktyā. Just like you can imagine that if you have got profound love for a person, either for your children or for your wife, then you'll always think of them. You can not be without thinking of them for a second, this is practice only.
So if we transfer this power of thinking to Kṛṣṇa, that is our perfection of life. We are thinking, we can not stay without thinking for a moment but if we think Kṛṣṇa and His pastimes then our life is perfect, that is Kṛṣṇa consciousness. Yathā sujātayā bhaktyā: but this situation is possible by advanced devotional service—sujātayā bhaktyā. Śuddhyet: that means so long we are thinking of Kṛṣṇa and His pastimes we are being purified, purified. If you can not think then you must hear therefore this is the opportunity.
