Quote from American Heritage Dictionary:

"Lack of concern. Having no marked feeling for one way or the other; not liking or disliking; not active or involved. Neutral."

Description:

INDIFFERENCE is the archetype of a youth who is not concerned about the sounds from the surrounding world. This androgyne walks indifferent between the jackal, the shadow side, yakking about the past, and the Serplion of creativity, exulting into the future.

Slipshod, ambivalent, careless to outer appearance, the perennial youth wanders in and out, using his staff as a balancer between planetary forces rather than leaning on it for support or guidance. With eyes shut to surroundings, INDIFFERENCE takes what comes in the moment, anticipating nothing, merrily experiencing the whole of life as it evolves.

Interpreted use:

Shut your ears to the noises around you. Rely on your direct Knowing to keep an inner balance.

Reversed (card received upside down):

You listen to the yakkings and roarings; the past and the future intimidate you; stop lest you fall off your structure.
