New video with nice graphics to illustrate the meaning:Bhante Anandajoti: Devolution and Evolutionhttp://www.youtube.com/watch?v=JFaoyp_wrlY
This video is built around a talk given in the Vivekavana Buddhist Society, Bukit Mertajam, Penang, Malaysia on January 6th 2013.
The talk is illustrated with infographics describing the planes of existence and with photographs and complimentary text.
The talk describes the various ways the universe comes to destruction, and how it re-evolves.
It also talks about the moral devolution of humans, before a reversal happens which eventually leads to the emergence of Metteyya (Maitreya) Buddha.
The talk is mainly based on two discourses in the Dīghanikāya, Aggaññasutta (DN 27) and Cakkavattisīhanādasutta (DN 26).
The first video in this series on The Planes of Existence is here: http://www.youtube.com/watch?v=GzPIeCaV-is
