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-vidhim, and act according to your whims, then there is no question of perfection. Na sa siddhim avāp..., na sukham, like that. The śāstra-vidhim (indistinct). Rūpa Gosvāmī also advised like that,
- pañcarātra-vidhiṁ vinā
- aikāntikī harer bhaktir
- utpātāyaiva kalpate
- (Brs. 1.2.101)
There are so many they have invented. Just like Hare Kṛṣṇa mantra is prescribed in the śāstras, and they have invented so many. Although there is the name of the Supreme Lord, still you have to follow the śāstra. If you say Rāma Rāma Rāma, Rādhe Rādhe Rādhe, Kṛṣṇa, there are so many mentioned. That is also name, but you have to follow the śāstra. Śāstra says:
- Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa Hare Hare
- Hare Rāma Hare Rāma Rāma Rāma Hare Hare
You have to take that. Not that you can say, nitāi-gaura rādhe-śyāma, hare kṛṣṇa hare rāma, no. Why? Is there any in the śāstra? No, you have invented. What is the value of your invention? You are not perfect. But they like that "It is my guru, I have got some followers, I invent some type of chanting." This is nonsense. You must follow, mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). You cannot invent.
