the first five tattvas (mahābhūtāni) are

earth
water
air
ether
fire

the earth is real! only my superficial contact with the earth is not real.
the water is real. only my superficial contact with the water is not real.
the air i breathe is real. my superficial contact with the air is not real.
ether is real. only my superficial contact with the ether is not real.
fire is real. only my superficial contact with the fire is not real.

there are 36 tattva’s

extracted from the teachings of Devi as written in Daniel Odier’s tantric quest

the word “tantra” comes from the root “tan” which means wide-ranging, whole. it also evokes the weave of a fabric.
