Who is he?

He is a dreamer,
His boundless mind beams
Into infinite universes,
Imagination bursting seams,
Defying this human hearse.

He is a thinker,
Patiently raking leaves
To reveal the ground beneath.
Mountains of sand he sieves
Leaving diamonds upon the sheath.

He is an explorer,
Whose fuel for adventure
Burns away his fears.
Rays bursting from centre,
Traveling millions of lightyears.

He is a giver,
Like mist over the mountain,
His logic leads his heart.
Many sip from the fountain,
But few understand his part.

He is my brother.
Strength of a hurricane,
Vast as the sea,
Gentle as the rain,
Rooted as the shepherd’s tree.

Yet I cannot define him
For that would confine him.
One cannot catch the traveling light,
But simply marvel at its sight.
