If one established in Brahman breaks even a twig of a living being's life, he has committed the sin of killing his own guru, and all the teachings he received are rendered false. He was told in initiation to behold his own true Self, yet he spends his time praising his own image. Through envy toward other beings, his knowledge of Brahman has been stolen by a thief. He tells others the lessons he has memorized while harboring division and anger in his belly. Says Tuka, he wastes his speech in both slander and flattery.
