Are there other non-physical sources, besides your higher self, from which you can gather spiritual information? You bet, and many of these entities are all too eager to tell you how to run your life even though they are entirely unqualified to do so.
Like humans, spirits are: nice, not-so-nice, neutral, and can be a combination of all the above. It's imperative to vet all extrasensory information to make sure it's coming from a credible source like your higher self.
You will need discernment in the spiritual realm just as much as you do in your physical life. You wouldn't walk up to a stranger on the street and ask if it's a good idea to buy a business and then take whatever they say as absolute truth – would you? Nope. The same goes for the spiritual world.
When looking for spiritual guidance, you don't want to take advice from the first disembodied voice that comes your way without investigation. Compare the information you get with what you know to be true in your heart from your experience and consult trusted experts and loved ones for help with important decisions.
My spiritual teachers have taught me to "test the spirits" to see where they are from and the validity of what they are communicating. One way to test a spirit is simply by asking. Ask if they are of the light and to back-up what they are saying. If they get offended or fight back by your line of questioning, tell them no thanks and send them on their way.
There are a few more things to keep in mind as you consider the validity and helpfulness of information from a spiritual source. Helpful spirits and your higher self will never feel intrusive or demanding. Also, truly helpful spirits are never panicked, and they don't bargain or give ultimatums. Be vigilant for those who say you must do something now, or it will never happen. It's most likely a trick to get you to make rash and unhelpful decisions.
As a rule-of-thumb, watch closely the energies that come in when receiving intuitive information. If it doesn't feel right, it probably isn't.

By birthright, you come with your unique life path and purpose, making you the best person to make decisions about your life. Your higher self and Creator know your purpose and what it will take to grow into a more authentic version of yourself. They are your safe go-to for spiritual guidance.
We all need help and advice from time-to-time, but the best mentors and teachers, whether on the physical or spiritual plane, will always lead you back to your truth and hold you 100% accountable for your own life. Protect yourself by taking full responsibility for your life. Taking this responsibility is where your real power lies and will prevent you from falling into the trap of needing constant external validation.
To further protect yourself spiritually, ground your body, and set a strong intention to only receive guidance from the higher self before listening for intuitive information.
