Gravitas is the Latin root for the English "gravity." It means weightiness, substance, dignified demeanor and has overtones of ground, earth, roots. When we have gravitas, we are coming from a deep and connected place.
Levitas is the Yang counterpart to the Yin gravitas. It is the Latin root for our words "levity" and "levitate." It means lightness, playfulness, spontaneity and has overtones of space. When we have levitas, we are not too serious and we are not stuck.
To encourage gravitas, use the yinning and yanging of the legs exercise and other grounding methods; think before speaking; act with special care. To encourage levitas, use the opening the crown exercise, smile, giggle, quip, let go . . .
