The door to heaven is open to us at any time we are willing to accept that we are of absolutely no importance. The bars of our own hell - the “mind-forged manacles” as Blake put it - are our attempts to justify ourselves or prove our self-worth. Accept that none of this matters and we can see that heaven is all around us. It is there in a child’s smile, in the rain that waters the earth, even in the maggots that rise in new life from dead meat. All around us is evidence that life and love are eternal and unbroken by strife and suffering.
