Though I lie within your own body
yet you care not enough to see
I might be lighter than the invisible air
yet I can make you do the heaviest deed.
When your body refuses to work,
and when your senses tend to die,
this is me shouting inside,
shouting for you to give one more try.
I may not be the strongest of all,
and I may not be an easy to find,
but in the times you feel alone and weak,
I promise I can walk you down this line.
