At certain moments, Biogenic Nutrition alone cannot any more guarantee our mental and physical health will remain intact, because it may become impossible to still eat real biogenic food, however much one might like to. This may occur when several of the Forces ("Angels") have been turned/ turning from good  into  bad, from white into black as is symbolized in the chess-"game" (the Art of Asha) :for instance when food gets polluted, poisoned, and/ or the Air, the Water, the Earth, in short: all of the elements necessary for producing and processing our food. 

When those Forces  ("Angels") themselves are under threat, the only thing that will remain available for us will then be the very strong protection, by purification and cleansing, the   Ayurvedic herbs and "Ghi" may offer our organism, plus the power that is added  to the dedicated production and eating of food ("Prasadam") by spiritual awareness .

Detailed knowledge on the usage of herbs in the Essene biogenic way of nutrition has been lost, but by going back a little further, to the common origin in Vedic times we can still find, for instance in the Vedic scriptures,  a   very accurate science on this subject.

Besides the way of food preparation and the adherent philosophy, also regarding the way of eating it, of course there are still several  other  interesting vedic traditions, such as the use of the "Tongue-scraper".
