I was thinking of starting to drink my herbal tea by using the sun's heat.
Basically, there are three major sources of prana: solar prana, air
> and ground prana. Solar prana is prana from sunlight. It invigorates
> whole body and promotes good health. It can be obtained by sunbathing
> exposure to sunlight for about five to ten minutes and by drinking
> that has been exposed to sunlight.
