Even if you don't do anything, simply if you kindly take the trouble of coming here and just try to hear about Kṛṣṇa sincerely, then your life will be successful. This is called bhakti. Kevalayā bhaktyā. Simply by executing devotional service And there are nine different types of devotional services, out of which, even if you accept one, your life is successful. This is called kevalayā bhaktyā. Just like Parīkṣit Mahārāja. At the last stage of his life he was cursed by a brāhmaṇa boy to die within seven days. So within seven days he had to prepare himself for the next birth. So he was little perplexed, and all the great saintly persons, sages—because he was emperor of the world—so they came. They consulted. It was decided that "You hear Śrīmad-Bhāgavatam the seven days." That is The Śukadeva Gosvāmī spoke, and he, listened from Śukadeva, and he became perfect within seven days. Therefore in India they observe this Bhagavat-saptāha. That is simply official. Actually, nobody hears very seriously.
So śravaṇam is so perfect also. Parīkṣit Mahārāja attained perfection simply by hearing seven days. Similarly, Śukadeva Gosvāmī, he also attained perfection by speaking seven days to Parīkṣit Mahārāja. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇam (SB 7.5.23) . Prahlāda Mahārāja, he was put into so many difficulties by his atheist father, Hiraṇyakaśipu, but he was simply remembering Nārāyaṇa, Kṛṣṇa. Because he was a child, five years old, how he can fight with his father? His father was the greatest demon, powerful, and he was against the child. So he used to simply think of Kṛṣṇa, smaraṇam. Pāda-sevanam: Lakṣmī, goddess of fortune, she simply engaged herself in massaging the lotus feet of Viṣṇu. Pāda-sevanam. Arcanam: Pṛthu Mahārāja, he engaged himself in the arcana. Vandanaṁ. Dāsyam: Hanumān. Akrūra, Akrūra, he simply offered prayers to Kṛṣṇa. Akrūra came to Kṛṣṇa Balarāma to take Them to Mathurā. So he got salvation simply by offering prayers. Vandanaṁ dāsyam. Hanumān, he simply offered his bodily service to Lord Rāmacandra. He got perfection. So śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam, arcanaṁ vandanaṁ dāsyaṁ sakhyam... Arjuna. Arjuna simply kept friendship with Kṛṣṇa. He got perfection. Sakhyam.
