In “Beyond Heaven”Rev. Clairissa considers the importance of remembering what matters whatever the conditions, even when we find ourselves caught up in the heavenly world of fleeting pleasures, as can happen in the realm of the devas (heavenly beings), in the Buddhist teaching on the Six Worlds. 

She refers to the teaching of Great Master Eihei Dōgen (1200-1253) in the Shōbōgenzō, translated by Rev. Master Hubert Nearman, Chapter 8 Keisei Sanshoku – On 'The Rippling of a Valley Stream, The Contour of a Mountain.'
