One who has no perception of Guru’s words is far inferior than an animal who eats hay and grass and yields nectar like milk.
According to Hindu mythology, cowdung and cow's urine are considered sacred but cursed is a human body that eats elixir- like food and spreads filth all around.
Those who take the support of the knowledgeable sermons of the True Guru and practice these in their life are superb saintly persons. On the contrary, those who shy away from the teachings of the True Guru are low of status, evil and foolish.
By meditation on His name, such saintly persons themselves become the fountains of elixir-like Naam. Those who are bereft of the words of the Guru and are engrossed in maya are scary like poisonous snakes and full of venom. (201)
