The Story of Usir, isis and Heru (Part 4- Shu and Tefnut)

Then RA took another little bit of his body and he made his son 'SHU'.

SHU is SPACE and AIR. SHU is the space around you and this space contains air. 

SHU is also the breeze that blows. SHU allows you to be able to breathe.

Then RA took another little bit of his body and made his daughter 'TEFNUT'.

TEFNUT represents moisture, such as rain.

Rain allows plants to grow and it brings water for people to live.

TEFNUT is the powerful strength which is in the ocean of creation and she is the source of vitality for all living things.
