avaiṣṇava-mukhodgīrṇaṁ pūtaṁ hari-kathāmṛtam śravaṇaṁ naiva kartavyaṁ sarpocchiṣṭaṁ yathā payaḥ

Unless one is a fully unalloyed devotee of the Lord, one should not try to describe the pastimes of Krsna in poetry, for it will be only mundane. There are many descriptions of Krsna's Bhagavad-gita written by persons whose consciousness is mundane and who are not qualified by pure devotion. Although they attempted to write transcendental literature, they could not fully engage even a single devotee in Krsna's service. Such literature is mundane, and therefore, as warned by Sri Sanatana Gosvami, one should not touch it.
