These are the remarks of ācāryas like Vīrarāghava Ācārya and Vijayadhvaja. To desire anything other than devotional service will diminish one's freedom from material desires, but when one is free from all such desires one is called nivṛtta-tarṣaiḥ (SB 10.1.4).
Vinā paśu-ghnāt. The word paśu means "animal." An animal killer, paśu-ghna, cannot enter into Kṛṣṇa consciousness. In our Kṛṣṇa consciousness movement, therefore, animal killing is completely prohibited.
Uttamaśloka-guṇānuvādāt. The word uttamaśloka means "one who is famous as the best of those who are good." The Lord is good in all circumstances. That is His natural reputation. His goodness is unlimited, and He uses it unlimitedly. A devotee is also sometimes described as uttamaśloka, meaning that he is eager to glorify the Supreme Personality of Godhead or the Lord's devotees. Glorifying the Lord and glorifying the Lord's devotees are the same.
