Uttama, uttama means udgata-tama. This material world is tama, ignorance, darkness. And Kṛṣṇa is beyond this material world; therefore He is called para. Para means transcendental. So uttama-śloka. So when we offer our prayers to Kṛṣṇa, they are not ordinary words. Therefore those who are not liberated soul, they cannot offer prayers actually. We have to repeat the prayers offered by liberated soul, not by ordinary man. Because he is not yet uttama, he is not yet in the transcendental platform. Therefore we don't allow songs which are not sung by liberated souls like Bhaktivinoda Ṭhākura, Narottama dāsa Ṭhākura. They are liberated souls. We don't allow any literature which is not given by liberated soul. Literatures, they are always following Vedic principles. Vedas, the original transcendental literature, and any literature which is produced under the guidance of Vedic literature, that is also nice. That is perfect. Therefore whenever we write something, we give immediately Vedic evidence. We give some Sanskrit verse. This means that we are not manufacturing ourself. What we have heard from the paramparā system, from higher authorities, we are presenting, simply, in our own language, and the evidence is this Vedic verse. This is perfect literature.
So whimsically, we cannot write any poetry for Kṛṣṇa. That is not possible. That will create havoc. Śrīla Rūpa Gosvāmī says,
- śruti-smṛti-purāṇādi-
- pañcarātra-vidhiṁ vinā
- aikāntikī harer bhaktir
- utpātāyaiva kalpate
- (Brs. 1.2.101)
Any devotional sentiment which is not supported by Vedas, śruti... Śruti means Veda, and smṛti means corollary to the Veda, or things which are written in corroboration with the Vedic ideas... That is called smṛti. Just like Bhagavad-gītā is smṛti. Bhagavad-gītā, the purpose of Bhagavad-gītā is the same as the Vedas, but it is not directly Veda; therefore it is called smṛti. Śruti-smṛti-purāṇādi (Brs. 1.2.101). The Purāṇas, there are eighteen Purāṇas. Purāṇādi means Rāmāyaṇa, Mahābhārata also. Śruti-smṛti-purāṇādi-pañcarātra-vidhiṁ vinā (Brs. 1.2.101). Pañcarātra-vidhi, given by Nārada Muni for worshiping the Deity. We are worshiping the Deity under the pañcarātra-vidhi. So Rūpa Gosvāmī says that "Any devotional service which has no reference with śruti, smṛti, purāṇa, pañcarātra, that is simply a disturbance. Simply disturbance, creating disturbance." We cannot manufacture. Sometimes we are questioned, "Can we do this? Can we do that?" Of course, it is good. But there is no need of manufacturing some idea. Whatever idea is already there, follow strictly.
