To those of us who judge unknowingly, or by deliberation I say this
That when, in judging others, we ourselves should exercise
Synchronous similar examinations, of our own minds
That we miss not those faults we own, and yet ignore
When serpent like we hiss, transfixed outside the others door
Obsessed, enabling words formed deep in the abyss
To travel from our minds so blind, to scornful lips
Words born of arrogance, part of ourselves we do not see
Insidious, they lie in us, the same as that we mock in he
Those faults of others that of which we all do moan
Forgetful all the time, of those immortal words
Let him who has no sin, cast first the stone
