Longing's Song

I'm the catnip's scent
I'm the purring sound
In pursuit of lust
I'm the feral hound

I'm the rhyming source
I'm its ceaseless caw
In the timbered heart
I'm the pouncing maw

I'm the empty tick
I'm the timeless hell
I'm the drowning flesh
In the wishing well

I'm the grasping want
I'm the craving tongue
In abysmal lull
I'm the longing's song
