As the developing human being has left behind the animal elements from the former zodiac signs (and eras) ie: Cancer: moodiness/self-pity; Gemini: ego-trap/childish behavior; Scorpio: self-destructive/sign of death etc., after Scorpio we come to the sign of Sagittarius which is half animal and half human. And that means to me that the human being as a whole has the chance to move forward, and leave the animal elements and tendencies behind, making space for the new to come.
After the death of the old (Scorpio), comes the Resurrection. But not yet, as Sagittarius is preparing the way for the Ophiuchus to rise forth. The arrow of Sagittarius is pointing in the middle of the Galaxy. Therefore, we as humanity have the chance to evolve and ascend (our consciousness) to the new Earth, right now, as the final Kalpa approaches. Then, the humanity will have the chance to work hard and climb the mountain (Capricorn), giving then space for the humanitarian (Aquarius) to introduce his new visions for humanity. The final step/era is the vast calm wisdom of Pisces, that spreads as an ocean, which can last for a thousand years... ~
