At the threshold that divides the elemental and etheric worlds, Are Thoresen encounters two spiritual entities – Vidar and Balder, 'guardians of the threshold' – whose task is to protect the spiritual border from uninitiated intruders. Building on previous reports, Encounters with Vidar offers startling new esoteric teachings, gleaned – through processes of spiritual knowledge – from these enigmatic gods. Here, Vidar and Balder emphasize the importance of clairaudience as opposed to clairvoyance (the latter particularly being open to attack from adversary beings). Through the process of working with the communications, the author begins to experience a transformation of his head chakras, leading to an awakening of 'spiritual ears'. Whilst clairvoyance is like reading the holy script, clairaudience is akin to hearing the holy script, he learns.

Amongst the wealth of fresh insights revealed here are the 'fourth aspect of the soul' (or 'time-karma-Christ'); the task of eurythmy today; the whereabouts of the contents of the School of Spiritual Science; and the work of 'Vulcan beings' and other planetary entities. Thoresen offers reflections on his travels to western England (with its connections to Troy) and southern Spain (with its legacy of Moorish occupation). His intention is not to create new dogmas or beliefs, but to testify to the living reality of metaphysical dimensions of reality – and humanity's latent ability to access them.
