Note that the crucifix is different from CARD X.
Aquarius represents 'The Father'
Scorpio represents 'The Son'
Taurus and Leo represent 'The Holy Spirit'
The pairings appear different if we view the cross and the pairings as an x-axis and y-axis.
Aquarius (AIR) and Leo (FIRE) are associated with male energy.
Taurus (EARTH) and Scorpio (WATER) are associated with feminine energy.
Asking why and understanding why a difference exists is another part of the journey.
