We Envy Them What We Think

We envy them what we think is their freedom of the sky
But like most of us to most of them borders too do apply
They dare not venture into another of their species territory
Most birds restricted by the limits of their borders or so 'twould seem to be
Einstein so right in his theory that all life forms to each other relate
All things in Nature have in them the power to re-create
Us humans too are of Nature why otherwise pretend
Our life journey like all journeys will come to an end
The lark for to sing up to the clouds does fly
The natural instincts born in him he cannot deny
Nature did not intend him to sing on bush or on tree
We only are what Nature meant us to be
Like all other life forms we are part of Nature it does seem to me
Though with that sort of thinking many would disagree.
