The inspiration of the poet is general, and that of the Bible unique; but there still remains a special kind to which Blake, like many other mystics, laid claim.
When Blake was perplexed at Felpham, he referred to his spiritual guides, who were in their turn subject to God. They, according to him, were the real authors and inspirers of his prophetic books. This sort of language was rare in the eighteenth century, but is quite familiar to readers of theosophical books, ancient or modern.
They teach that there are seven planes of consciousness from the physical to the mahaparanirvanic, which together make up the cosmos. The two highest planes are beyond the reach of human conception; but there are not a few to-day who claim to have attained to the fifth nirvanic plane. Here the consciousness is so finely developed, and its vibrations respond so readily, that the subject comes into touch with other intelligences, and often submits to them entirely for guidance.
In St Paul's day this teaching was familiar at Ephesus in the form of gnosticism. He did not disbelieve in the reality of the seven planes, but he disagreed with the gnostics in their blind faith in the trustworthiness of the guides. He believed that many of them were so evil that when Christians became conscious of them, they needed the whole armour of God to protect them against their wiles. Here is the difference between the Christian and pantheistic teaching. The pantheist thinks that because a thing is spiritual it is therefore holy and good; Christianity believes in fallen spiritual beings. The pantheist believes that to reach the nirvanic plane is to attain to holiness; Christianity says that all the planes of the cosmos are tainted, and if one reached even the seventh, one would still have need of cleansing. Theosophy keeps one for ever within the cosmic circle; Christianity lifts one beyond the circle into the ascended Christ, and teaches that one is safe on the different subtle planes of consciousness only while one abides in Him. Doubtless there are good guides, but the danger is great because it is so difficult to try the spirits.
Blake here as elsewhere wavers between the two views. With certain reservations he dips on the Christian side. He travels round the cosmos, but in a spiral; and the top of his spiral--his Jacob's Ladder--reaches not to the seventh plane but to the Throne of God, which is far above the charmed circle. Hence man is able to climb beyond the defiled cosmos into the pure heaven of God. That is his redemption.
