He began a reading career on Edinburgh Festival fringe in 1960, with the London poets Pete Brown, Mike Horovitz and Libby Houston. In 1965 Jackson founded the yearly series of readings during the Edinburgh Festival in the Traverse Theatre . These readings became a platform for the Liverpool poetsBrian Patten, Adrian Henri and Roger McGough and for the older Scottish poets Edwin Morgan, Robert Garioch and Norman McCaig. Hamish Henderson brought folk singers. Pentangle played there, as did The Scaffold. Poets such as Pete Morgan and Pete Roche first appeared at these Traverse readings. Jackson went on from this time till the early seventies to give hundreds of readings throughout Britain, often solo, but mostly with Patten, Mitchell, Morgan, Houston and others of the poets mentioned above. In 1973 Jackson announced that he was retiring from the "reading scene". The time had come he said "to obey the poetry", rather than merely purveying it to others. This move of Jackson’s only makes sense when it is considered that his poetry had never been one of nature description or social anecdote, but had themes of self-inquisition and self-undoing. Heart of the Sun has a long introduction entitled "Reasons for the Work", describing his poetic evolution through the years since the decision to ‘retire’. Jackson had always had considerable philosophical and historical interests and a main feature of the introduction is his account of how experiences of his own led him to the work of Rudolf Steiner, the Austrian Christian initiate. This new phase in Jackson’s life led to the writing of short stories, in italics because they are not so much realist, but have something of the nature of myth and fable. He was also writing ideas pieces, investigating and expressing ‘the spirit forces’ at work in our time.

He self-publishedUnderwater Wedding in 1961. In 1968 he was published in Penguin Modern Poets 12 and in 1969 by the avant gardeFulcrum Press. In June 1971 the whole issue of Lines Review 37, the Scottish literary magazine, was devoted to Jackson’s essay "The Knitted Claymore", which expressed his conviction that rising nationalist sentiment in Scotland was infiltrating and distorting the realm of literature. As could be expected, the essay was widely welcomed and widely attacked.
