A common method
The 48-hour yes or no
A popular way to ask for signs is to name one specific sign and a deadline. The article "How To Ask For Signs From Your Spirit Guides" describes asking to be shown a yellow heart within 48 hours: if it appears, the answer is yes, and if not, no. Choosing the sign in advance is smart, because it stops you from treating everything as an answer afterward. Another widely read guide, "10 Simple Steps To Connect With Your Spirit Guides," pitches a spiritual practice of just 3 minutes a day.
