The mind can, by force of clarity, see the common deep thoughts of mankind as visions

Meditation creates clearness.

The clearness from the dissolved and evaporated thoughts and contents will widen the mind out towards the borders, behind which the collective common human structures are found: the images in time.

These common deep thoughts of mankind, can the mind, by force of its increased clarity – the astral state - see as visions: primordial images, religious images and structures, symbols, wisdom-figures, figures from fairy tales, higher worlds, other dimensions.

In short: the astral worlds.
