Im a Gemini, what does it mean when they say a "mutable" sign?

...mutable signs and houses are 'change able'.

that is they are able to more readily adapt/accomodate characteristic cardinal or fixed energy (mind) styles.

mutable air (gemini) is able to change mind (as purpose) or thoughts. and therefore best as communicators (messengers) of ideas to/of others.

mutable earth (virgo) is able to change mind (as purpose to matters of practice) for the serving of self in relationship. and therefore best as communicators (practitioners) of knowledge in organization. (or what is referred to as classificationists).

mutable fire (sagittarius) is able to change mind (as purpose to matters of spirit) for the aspirations to ambitiously fullfill self realization. and therefore respond best as communicators of higher purpose or vision as may be selfishly realized...(but not necessarily shared to others).

mutable water (pisces) is able to change mind (as purpose to be sympathetic to self of the world and as may be related by their personal soul or feelings. and therefore respond best as feeling translationists of others though by their own vessels. so responding in capacities which relate the feelings and/or mental determinations ....(thoughtfully-gemini ~ orderly-pisces~ visually-sagittarius~).

mutable signs and mutable houses enable self determined (fixed) energies to be active (cardinal) for the purpose. such as taurus through to cancer by gemini. such as leo through to libra by virgo. such as scorpio~eagle through to capricorn by sagittarius. such as aquarius through to aries by pisces.

that will be 500 $ please and thank you.

be well
