Weaknesses are so powerful,
They show the flaws of strength
Man in all his wisdom and evolution
Fails to comprehend simple nature
We have drawn from nature
Suckled upon its left breast
Toyed with the right one
We have seen but half its light
Dogs bark, Alsatian ones, Bull ones, Wolfhound ones , Greyhound ones and all sorts, black ones, grey ones, yellow ones, white ones, they all have at least one thing in common, they bark. Everyone sees them and calls them a dog, they love the variety, they may have preference but are mostly cared for equally.
Trees stand, some short, some tall, some fat, some thin, they sometimes dance to the rhythm of the wind, some have leaves, some don't , some shed, some don't , some have fruits , some don't , they are all trees, nobody despises a tree because of it's bark, different tree barks could make useful herbs and other useful materials. people love different trees, they even make good shades in scorching summer.
In the human sphere, we have all sorts, tall, short, fat , thin and in beautiful colors- with all other variegated features but what we see is what we do not have in common: culture, religion, color... difference. Where there is no difference, we fabricate it, we fabricate inferiority and superiority, we create deplorable history, lies, we create vain interests and fight unjustly to fulfill them.
Nature prides in uniting varieties into a coherent beauty.
