As mentioned, Edgar Cayce’s chart gives hints of spiritual ability, but not really at a psychic level. Many other psychics don’t have superior or special birth charts as well. In fact, many have charts that are far worse than his.
3 other reasons someone receives a psychic calling are: a high level of personal cultivation, ancestral influence and the urgency of the times.
Edgar Cayce once said that astrology and birth charts are just general tendencies. They do not dictate everything that happens in your life. I agree with this. Ironically, you understand your birth chart so as to help you go beyond your birth chart. But sheer effort is required. It comes in many forms, and are not limited to the following: meditation, good reading habits, good moral character, good deeds, giving to charity, being kind to people, maintaining and conserving your environment. Hence people with more spiritual charts can find ways to develop their material abilities. Conversely, those who manifest wealth easily can find ways to hone their spiritual instincts. At times, powerful spirits may ‘overlook’ strong, well-balanced birth charts and choose individuals with weak, unbalanced birth charts and poor family backgrounds, but are humble, gentle and kind. We don’t always know the exact criteria that the deities follow when choosing their 'hosts'. But we do know that generally, the good ones will connect with good people. So if you want to avoid the bad ones, just be a good person.
Ancestral spirits will bless their descendants. If your ancestors were endowed with great spiritual powers, these same powers will usually follow you and your descendants. For Edgar Cayce’s case, in my opinion, his guide didn’t come from his ancestors but from a group of beings that also influenced Helena Blavatsky and many others.
I believe these beings wanted to introduce a new spiritual age to save humankind from destruction. Edgar Cayce lived through 2 turbulent world wars. It was a scary and dangerous era. He also wrongly predicted that the world would end before the 21st century. Ironically, this might have created the opposite effect of many spiritual people interceding and raising the overall vibration of the human race, thus delaying the end of the world.
The gods / spirits / guardian angels / higher deities run their own time-tables. What goes on in the spiritual realm is a reflection of what goes on in the material realm, and vice versa. Important political events, pandemics, wars follow their own cycles. At crucial times, these higher guides may be ‘activated’ to help humankind overcome a dangerous crisis. They find themselves caught between a rock and a hard place, and will eventually look for people who may not fit the bill, but have good hearts.
PS: I have a lot more to say about the heavenly mandate running its own time-table & cycles. I personally think we are living in a very crucial time, perhaps even more crucial than Edgar Cayce's.
Sometimes, when I look at what is happening around me (in Singapore), I am bewildered. And I no longer dare to read international news, because I know I will be even more bewildered. I shut myself out, and down.
