Deep in the ocean in a midnight zone where no light can get in, the jellyfish known as the Stygiomedusa gigantea thrives without possessing so much as a bone, tooth or brain to weigh it down. These deep-sea jellyfish are proof that one doesn’t have to be heavy to be deep. This message was brought to you by the water-sign trine of Mercury and Saturn.

ARIES (March 21-April 19). It’s good to have someone else be vigilant on your behalf, even if it means they doubt you and challenge your ideas. Having to defend yourself to some degree will improve your stance so you can follow through with full confidence.

TAURUS (April 20-May 20). Every goal comes with a price — whether in terms of time, effort, emotional energy or material resources. It can be a little awkward, but it’s usually much better to ask, “How much?” up front, and, wherever possible, get it in writing.

GEMINI (May 21-June 21). Are you stepping into power or handing it off? If something excites you, run toward it. Don’t get distracted by what others think you should be doing. Focus on what makes you feel alive and in control.

CANCER (June 22-July 22). Apply what you learned. This will prove to you and everyone else that you’ve learned it. The skill will inform other things in your life and have far-reaching effects impossible to know at this juncture.

LEO (July 23-Aug. 22). You’ll be seduced by a dream of what could be. And while it’s great to think about the future, don’t get so lost in those glittering potentials that you neglect the magic before you, because that’s the opportunity that makes the rest possible.

VIRGO (Aug. 23-Sept. 22). Some talk about their weaknesses so much, they almost glorify them. Inner strengths seem inappropriate to talk about. You don’t want people to think you’re bragging. But there are people who would be inspired by the power you’ve cultivated.

LIBRA (Sept. 23-Oct. 23). Many are drawn to your spark, but they do not all deserve your VIP treatment. Who sees the real you — the “you” that you want to be? Stick with those fans; they’ll keep your soul shining.

SCORPIO (Oct. 24-Nov. 21). Today plays out like some kind of video game challenge. Pick one thing and aim straight for it, no matter what comes at you from the sides. And if you need help fending off threats in the periphery, the world is your prop department. Use what’s around you like a pro.

SAGITTARIUS (Nov. 22-Dec. 21). When do you walk away from something? Simple. When keeping it around is more trouble than it’s worth. Life’s got an expiration date on everything — even if it’s not printed on the label. You’ll know when to let go.

CAPRICORN (Dec. 22-Jan. 19). Whether the water is 10 feet or 100 feet deep, the swimming is the same. So there’s really no point in thinking about how far down the bottom is. Instead, focus on your strokes, and when those get tedious, float. You’re doing great.

AQUARIUS (Jan. 20-Feb. 18). Some people chase status like it’s a shiny object, while others pretend they don’t care at all. Both can be exhausting. This is a day to sit comfortably in the middle, valuing what matters without getting caught up in the chase.

PISCES (Feb. 19-March 20). Today’s project isn’t the one for cutting corners. Even if you see a “shortcut,” don’t take it because it’s a loop that will bring you right back to where you stand, precious time wasted. Instead, buckle up and get there on the trusted route.

TODAY’S BIRTHDAY (Oct. 21). You’re on the verge of something special and you have the butterflies in your stomach to prove it. As you act on what you believe, you’ll be on sure footing every step of the way, capable, efficient and effective. A mentor helps you take it to the next level. More highlights: A relationship is paradise. You’re a priority to someone special, and you take every opportunity to reciprocate. Taurus and Virgo adore you. Your lucky numbers are: 10, 3, 44, 15 and 28.
