How does the poet suggest that you identify the lion and the tiger? When can you do so, according to him?

The poet suggests that if a large and tawny beast in the jungle in the east advances towards us, then it is an Asian lion. We can identify it when it roars at us while we are dying with fear. When roaming, we come across a wild beast that is yellow in colour with black stripes, it is a Bengal tiger. We can identify it when it eats us.
