You may have learned in an elementary physics class that for every action there is an equal and opposite reaction; you may have balanced an equation to demonstrate that nothing may be lost or gained. Such is the calculation of Sir Isaac Newton; but it is not the calculation of William Blake. Blake adds into his equations factors which cannot be measured . Effects may be multiplied, divided, added, or subtracted by spiritual forces which act from the hearts, minds and imaginations of men. For good or ill there may be unintended consequences as a result of the status of the Soul. If a man is 'organized by Divine Providence for Spiritual communion' his choices will encourage the development of his spirit at the expense of self enhancement. If the Selfhood or false reasoning power dominates the mind, a man will 'not see spiritual agency' and will fail to recognise the connections among all things.
Milton, Plate 26 , (E 124)
"And every Natural Effect has a Spiritual Cause, and Not
A Natural: for a Natural Cause only seems, it is a Delusion
Of Ulro: & a ratio of the perishing Vegetable Memory."
Letters, To Butts, (E 724)
"But if we fear to do the dictates of our Angels & tremble at the
Tasks set before us. if we refuse to do Spiritual Acts. because of Natural
Fears or Natural Desires! Who can describe the dismal torments of such a
state!--I too well remember the Threats I heard!--If you who are organized
by Divine Providence for Spiritual communion. Refuse & bury your Talent in
the Earth even tho you should want Natural Bread. Sorrow & Desperation
pursues you thro life! & after death shame & confusion of face to eternity--
Every one in Eternity will leave you aghast at the Man who was crownd with
glory & honour by his brethren & betrayd their cause to their enemies. You
will be calld the base Judas who betrayd his Friend!"
Descriptive Catalog, (E 544)
"Reasons and opinions concerning acts, are not history.
Acts themselves alone are history, and these are neither the exclusive
property of Hume, Gibbon nor Voltaire, Echard, Rapin, Plutarch, nor
Herodotus. Tell me the Acts, O historian, and leave me to reason
upon them as I please; away with your reasoning and your rubbish.
All that is not action is not [P 45] worth reading. Tell me the What;
I do not want you to tell me the Why, and the How; I can find that
out myself, as well as you can, and I will not be fooled by you into
opinions, that you please to impose, to disbelieve what you think im-
probable or impossible. His opinions, who does not see spiritual
agency, is not worth any man's reading; he who rejects a fact because
it is improbable, must reject all History and retain doubts only."
In Auguries of Innocence Blake is showing that nothing can be viewed in isolation. Even the most distant effects have causes not attributable to natural events. Every act has consequences.

What is this spiritual agency other than connections among various happenings in this world and in the spiritual world. Acts performed in human lives influence the spiritual condition of the person who performs them and of others who are touched by them. Carelessness about the treatment of the weak and vulnerable is not innocent although the consequences may be unintended.
If we look only for natural causes and connect events only through what we can weigh and measure, we are not aware of the harm or good which results from ordinary or extraordinary acts. The outer and the inner are not distinct areas; what is done outwardly is a consequence of inner acts and affects the inner life as well as the outer life.
If a man choose to live according to outward considerations exclusively, his inner being will be starved and will atrophy.
Gospel of John Chapter 12  Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth.  While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.
