When I asked the Universe to give me a clear sign for going to an ayahuasca retreat in Peru - I turned on the radio and two men were discussing Peru.
When I asked which book I should start reading, (with four books in my hand), a robin landed on a branch in front of me. The keyword for robin is "Shamanism," so I started reading the book on shamans.
When I was going through a breakup and wanted confirmation, I asked to see a group/a lot of butterflies, more than 13. Turned the corner and saw 20 plus butterflies.
When I made a new friend and wondered if I should hang out with her, I looked up and saw a bunch of balloons floating in the sky.
When I was hesitant/reluctant about moving to the west side, and couldn't decide, I stopped at a traffic light. On a billboard read "move."
When I asked whether I should take my family to Peru, Brazil, Australia or Jamaica, a jeep pulled in front of me with a bumper sticker that read "Brasil."
When I was hesitant about a meeting with a producer, (sensing his ulterior motive), I asked the Universe to cancel the meeting for me if my instincts were correct. One hour before the meeting, the producer canceled the meeting. I didn't need to see him again.
When I was conflicted with whether I should teach or not, I asked for a sign. I looked to my left and saw the word "teach" painted across the side of a van.
When someone asked me out on a date, I asked to see one butterfly for no and two butterflies for yes. One butterfly flew across my face.
When I wondered whether it was time to get a new bed, I saw the word "mattress" on the side of a van, parked in the middle of the road - in front of my home.
When I asked if I should join a certain literary agent, I saw a poster that read, "The universe has your back. We got you."
When I was questioning my work, I saw on a license plate: GD KRMA.
When I ask for a sign, I trust whatever the Universe/guides show me. You can ask for animals, words, insects, places, people, flowers, numbers. Be as specific as you like. But only ask - if you are completely open to the answer. If you keep asking for different signs because you don't like your sign - you're not trusting in the universe. Give mixed signals and you'll get mixed signals.
