The work of the MERU Foundation
The work of Robert Gray (and also his collaboaration with Lynnclaire Dennis and their work to understand her near death experience)
The artist Hilma Af Klint
... and the remarkable Emma Kunz
Just a glimpse of the tip of the iceberg.
Please review and respond if inclined.
Be prepared for a mind bomb.
