You cannot write nonsense. You have to write something which corroborates with the Vedic injunction. That is called smṛti. You cannot manufacture anything. You should always remember that, "I am a teeny brain here, so I have to receive knowledge from superior sources." Then whatever knowledge you have received, if you can expand that in your . . . by your, I mean to say, capacity, that is called smṛti.
So there are two different kinds of Vedic literature. One section is called śruti, originally coming. Just like this Caitanya-caritāmṛta: this is a book written by Kṛṣṇa dāsa Kavirāja Gosvāmī, a great devotee of Lord Caitanya. It is called smṛti. Why? Everything written here is corroborating the Vedic literature. There is nothing suggestion, "I am a philosopher. I am a speculator. I think this will be like this." Here you'll see in every step he is quoting from Vedas. Caitanya Mahāprabhu is quoting. This is the topics between Sanātana Gosvāmī . . . this is the Vedic way.
Now that sage, a great sage, he is giving his conclusion that śrutir mātā pṛṣṭā diśati bhavad-ārādhana-vidhim (CC Madhya 22.6): "I have inquired so many Vedic literature. Now I am in conclusion that worshiping the Supreme Lord, that is the injunction of the . . . nothing more. Nothing more." The whole idea is . . . and that is confirmed by Bhagavad-gītā also. Kṛṣṇa says—in the Fifteenth Chapter you will find—vedaiś ca sarvair aham eva vedyam (BG 15.15). What is the purpose of Veda? The purpose of Veda is to understand Kṛṣṇa. That's all. If you can understand to some extent Kṛṣṇa, then your all Vedic studies finished. No more taking trouble. So we have to follow.
Now, here the great sage says that, "I have consulted all the Vedic process, all the Vedic literature, and I see that bhagavad-ārādhana-vidhi: the only injunction is that to worship the Supreme Lord." And similarly, in the Bhagavad-gītā it is confirmed by the Lord, vedaiś ca sarvair aham eva vedyam: "By Vedic study means I. One has to understand Me. That's all." If you try to understand Kṛṣṇa as far as possible through the reliable sources, through the bona fide sources, then your Vedic study is going on in Kṛṣṇa consciousness.
