Among the many connections between astrology and tarot is the fact that each planet that plays a significant role in the natal chart has corresponding tarot cards associated to it.
In astrology, the Sun is the symbol of identity, conscious ego, power, vitality, resilience, inspiration, asserting one’s leadership qualities. It’s associated with the Divine Masculine energy. Its motto would be "I am”.
