Bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19). That mad-deva, that "Kṛṣṇa, is my worshipable Deity only," this conclusion comes after many, many births of culturing knowledge, jñāna, yoga, karma. It is not so easy. Therefore we have to take shelter of such person who has taken Kṛṣṇa as the only shelter, vāsudevaḥ sarvam iti sa mahātmā (BG 7.19). We have to take shelter of such mahātmā, not others. Mad-deva, these are the different items, mad-deva-saṅgād guṇa-kīrtanān me. Not that now they have invented that "Why Hare Kṛṣṇa? We can chant śivo 'ham, śivo 'ham, om, om, kālī, kālī, durgā." They are all nonsense. They are all nonsense. Here bhakti-yoga means, here it is: guṇa-kīrtanān me. Not others. You cannot argue that "This is also good, that is also good." No compromise, kṛṣṇa-kīrtana. Just like Gosvāmīs, they said, kṛṣṇotkīrtana-gāna-nartana-parau. Not others. Utkīrtana, Hare Kṛṣṇa. Kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet (SB 12.3.51). These are the instructions. Śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23), not of Śiva, not of Brahmā, not of any other demigod. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam. Here also it says, guṇa-kīrtanān me.
So these are the items we should . . . Nirvaira-sāmyopaśamena putrā jihāsayā deha-geha (SB 5.5.11). This is also one of the important items, that I am executing devotional service, but I have no detachment from my family life. The bhakti-yoga means bhaktiḥ pareśānubhavo viraktir anyatra syāt (SB 11.2.42). That is bhakti-yoga. Everyone can test, "How much I have become detached from my, this worldly affection: this is my family, this is my country, this is my society, this is my son, this is my wife, this is my children." This is moha. Janasya moho 'yam ahaṁ mameti (SB 5.5.8). We have to give up this. If we have not been able to give up this attachment, worldly attachment, that means we are not making any progress. Therefore it is said clearly, deha-gehātmā. Eh? Buddheḥ. What is that? Jihāsayā deha-gehātma-buddheḥ. Ātma-buddheḥ. Deha-gehātma-buddheḥ. Everyone is thinking, "I am this body." Everyone is thinking, "This is my country," nationalism. "This is my socialism." "I am brāhmaṇa, I belong to the brāhmaṇas," "I belong to the kṣatriyas." "I belong to America." "I belong to India." This is deha-gehātma-buddheḥ, and yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13): anyone who is thinking like that, deha-gehātmā, sa eva go-kharaḥ, he is no better than the cows and the asses, animal. Deha-gehātma-buddheḥ is animal conception. One has to come to understand that "I am not this body, I am not this mind or intelligence." Ahaṁ brahmāsmi, "I am part and parcel of Kṛṣṇa, Paraṁ Brahman." Mamaivāṁśo jīva-bhūtaḥ (BG 15.7).
So in this way, if we practice according to the prescription, śāstra-vidhi, that is wanted. Not that without śāstra-vidhi you can become liberated. That is not possible. Yaḥ śāstra-vidhim utsṛjya vartate kāma-kārataḥ na sa siddhim avāpnoti (BG 16.23), Kṛṣṇa says. And if you give up śāstra-vidhi and act according to your whims, then there is no question of perfection.
