A renounced sage in the forest does not kill animals, but rather acquires skins from animals who have suffered natural death. According to a passage from Manu-saṁhitā, quoted by Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura, the word medhyaiḥ, or “pure,” indicates that while residing in the forest a sage may not accept honey-based liquors, animal flesh, fungus, mushrooms, horseradish or any hallucinogenic or intoxicating herbs, even those taken as so-called medicine.
