“Hastikaśīrṣa, it’s like cow’s milk. Milk changes into cream, cream gives rise to raw butter, raw butter becomes refined butter, refined butter becomes ghee, and ghee is supreme. Hastikaśīrṣa, it should be that when there’s milk, it’s only called milk and not called cream, butter, and ghee. Thus, when it turns into ghee, it’s only called ghee and not called milk, cream, and butter.
