People are so ignorant that they cannot understand what is the importance of this valuable human form of life. This is Prahlāda Mahārāja's instruction from the very beginning: durlabhaṁ mānuṣaṁ janma tad apy arthadam adhruvam. Kaumāra ācaret prājño dharmān bhāgavatan iha durlabhaṁ mānuṣaṁ (SB 7.6.1). Just like these small children, they are being trained up in this bhāgavata-dharma: śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23). Bhāgavata-dharma means hearing, chanting of the Supreme, glories of the Supreme Lord. Śravaṇaṁ kīrtanaṁ viṣṇoḥ. Not for others. If somebody says, "Yes, I am hearing always in the telephone. I am doing business," no, not that kind of hearing. Śravaṇaṁ kīrtanaṁ viṣṇoḥ. If you can contact Viṣṇu or His devotee, Vaiṣṇava, that is all right. Otherwise, you are simply wasting time. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam. Always, constantly thinking of Him. These are the bhakti ways.
There are nine different processes prescribed in the śāstra: śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇam pāda-sevanam arcanam . . . (SB 7.5.23). This is arcanam, worshiping the Deity in the temple. This is called arcanam. The Lord is called arca-vigrahaḥ, arca-avatāra. He is also incarnation, another incarnation of . . . arca-avatāra. He's giving facility to the devotees to handle Him. If you do not get the opportunity to serve the Lord, how you can be perfect? So this arca-vigrahaḥ is Lord's incarnation to give facilities to people like us who cannot see God everywhere. For the neophyte devotees, it is essential to worship the Deity. But if you simply worship the Deity without hearing about the Lord, śravaṇaṁ kīrtanam—these things are essential—then the Deity worship will be a burden. At a certain point, it will be a burden, and gradually it will be neglected, and the whole thing will be spoiled. So both things should continue: bhāgavata-mārga and pañcarātriki-mārga. Deity worship is pāñcarātriki-vidhi, and bhāgavata-mārga is hearing, chanting, like that. Both of them should be accepted, parallel line. Otherwise, one without the other will be later on troublesome. So you must continue.
