If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.” 
Stephen Hawking

"Expansion" is the limitless unfolding of  potential, of consciousness. The Upanishads teach that expansion is deeply tied to the idea of self-realisation, growth beyond the ego and even manifestation: “You are what your deep, driving desire is. As your desire is, so is your will. As your will is, so is your deed. As your deed is, so is your destiny. (Brihadaranyaka IV.4.5). As your psyche expands to encompass more of itself, expansion becomes an exploration of the limitless possibilities within. This card suggests you are ready for the adventure of a lifetime - the journey into the vastness of yourself, the universe, and the interconnectedness of all things.

Expansion Mantra: I embrace the journey within, unlocking my true potential, and connecting to the infinite possibilities of the universe.
