The poem is also full of questions - twelve in all. Perhaps Blake intends the poem to be less than easy to understand because he, too, had lots of questions he couldn't answer. The first question hints that this poem is not really about nature despite its title,
'...What immortal hand or eye could frame thy fearful symmetry?'
The 'immortal hand 'can only refer to God, and this gives the poem a religious theme that is continued through the remaining questions. Asking so many questions of God - especially the final question, which is a twist on the final line of stanza one, ('What immortal hand or eye / Dare frame thy fearful symmetry?') seems to suggest that Blake cannot understand how God could create an animal that is at one and the same time both beautiful and fearful, even evil.
At the end of stanza five, it is easy to imagine the tiger killing the Lamb, and, with the Lamb being given a capital 'L' it might refer to the 'Lamb of God' or Jesus Christ. Did Blake, who is known to have hated what he saw as God's 'natural religion' being misused by the leaders of mankind, mean not a tiger but a man? And that man has somehow destroyed Christ, or at least, what Christ was meant to stand for in the world? Is God crying at what he sees of how His creation ('watered heaven') has been ruined by mankind?
Certainly, Blake wrote this poem at a violent time in history, when England had attacked France soon after the French Revolution. This revolution began in the hope of freeing ordinary men from tyranny and the uncontrolled power of kings. It was meant to bring freedom and equality for ordinary people - something close to Blake's own heart. It does seem that there is irony, even sarcasm, in the two questions of stanza five: 'Did he smile his work to see? / Did he who made the Lamb make thee? 'Perhaps Blake meant 'Could he... 'when he wrote, 'Did he...'?
It is not easy to know what Blake really wanted for his readers in this strange and fascinating poem. But what cannot be doubted is power and beauty of the poem. Perhaps Blake just wanted his readers to feel this power and beauty and to ask themselves why our world should contain such opposites as goodness and evil, beauty and ugliness?
