Blake writes of learning experiences by which his characters thread their way through difficulties and delights. His point is to make his reader ever more capable of living in the Eternal dimension by learning to discard the impediments which he accumulates in the temporal world. By failing to see the direction he is headed because of the ups and downs of natural existence, man may lose sight of the Divine Guidance. Blake's advice is change one's perspective:
"To see a World in a Grain of Sand And a Heaven in a Wild Flower Hold Infinity in the palm of your hand And Eternity in an hour" (Auguries of Innocence)
Marriage of Heaven & Hell, Plate 5, (E 35) "In seed time learn, in harvest teach, in winter enjoy." Jerusalem, Plate 56, (E 206) "O daughters of despair! Rock the Cradle, and in mild melodies tell me where found What you have enwoven with so much tears & care? so much Tender artifice: to laugh: to weep: to learn: to know; Remember! recollect what dark befel in wintry days O it was lost for ever! and we found it not: it came And wept at our wintry Door: Look! look! behold! Gwendolen Is become a Clod of Clay! Merlin is a Worm of the Valley! Then Los uttered with Hammer & Anvil" Europe, Plate iii, (E 60) "Then tell me, what is the material world, and is it dead? He laughing answer'd: I will write a book on leaves of flowers, If you will feed me on love-thoughts, & give me now and then A cup of sparkling poetic fancies; so when I am tipsie, I'll sing to you to this soft lute; and shew you all alive The world, when every particle of dust breathes forth its joy. Milton, Plate 25 , (E 122) "Go forth Reapers with rejoicing. you sowed in tears But the time of your refreshing cometh, only a little moment Still abstain from pleasure & rest, in the labours of eternity And you shall Reap the whole Earth, from Pole to Pole! from Sea to Sea Begining at Jerusalems Inner Court, Lambeth ruin'd and given To the detestable Gods of Priam, to Apollo: and at the Asylum Given to Hercules, who labour in Tirzahs Looms for bread Who set Pleasure against Duty: who Create Olympic crowns To make Learning a burden & the Work of the Holy Spirit: Strife. T[o] Thor & cruel Odin who first reard the Polar Caves Lambeth mourns calling Jerusalem. she weeps & looks abroad For the Lords coming, that Jerusalem may overspread all Nations Crave not for the mortal & perishing delights, but leave them To the weak, and pity the weak as your infant care; Break not Forth in your wrath lest you also are vegetated by Tirzah Wait till the Judgement is past, till the Creation is consumed And then rush forward with me into the glorious spiritual Vegetation; the Supper of the Lamb & his Bride; and the Awaking of Albion our friend and ancient companion. So Los spoke. But lightnings of discontent broke on all sides round" Jerusalem, Plate 49, (E 199) "Remove from Albion, far remove these terrible surfaces. They are beginning to form Heavens & Hells in immense Circles: the Hells for food to the Heavens: food of torment, Food of despair: they drink the condemnd Soul & rejoice In cruel holiness, in their Heavens of Chastity & Uncircumcision Yet they are blameless & Iniquity must be imputed only To the State they are enterd into that they may be deliverd: Satan is the State of Death, & not a Human existence: But Luvah is named Satan, because he has enterd that State. A World where Man is by Nature the enemy of Man Because the Evil is Created into a State. that Men May be deliverd time after time evermore. Amen. Learn therefore O Sisters to distinguish the Eternal Human That walks about among the stones of fire in bliss & woe Alternate! from those States or Worlds in which the Spirit travels: This is the only means to Forgiveness of Enemies[.] Therefore remove from Albion these terrible Surfaces And let wild seas & rocks close up Jerusalem away from Plate 50 The Atlantic Mountains where Giants dwelt in Intellect; Now given to stony Druids, and Allegoric Generation To the Twelve Gods of Asia, the Spectres of those who Sleep: Sway'd by a Providence oppos'd to the Divine Lord Jesus: A murderous Providence! A Creation that groans, living on Death." Descriptive Catalogue, Page 52, (E 546) "they possess themselves of the bodies of mortal men, and shut the doors of mind and of thought, by placing Learning above Inspiration, O Artist! you may disbelieve all this, but it shall be at your own peril."
 ... the word of God came unto John the son of Zacharias in the wilderness.
 And he came into all the country about Jordan, preaching the baptism of repentance for the remission of sins;
 As it is written in the book of the words of Esaias the prophet, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
 Every valley shall be filled, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways shall be made smooth;
 And all flesh shall see the salvation of God.
 ...we glory in tribulations also: knowing that tribulation worketh patience;
 And patience, experience; and experience, hope:
 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
