I absolutely could use a less “controversial” word – as other teachers do. I’ve heard a teacher reference a pencil and another teacher (Vyasa, perhaps) used a cow. In class, I actually cited Swami J, of the Himalayan tradition, who used the example of a table in his commentary on the sūtras. Those are all great examples, simple examples; because, if you know English (assuming you are reading this text in it’s original language), the sight/sound of each of those words is associated with specific objects, which immediately come to mind. If you don’t know a word, it is meaningless to you. Nothing comes to mind or you think of something that feels off, not quite right. But, you don’t know the word, so you need more information.
