Had a similar meditation experience exept I heard a lady's voice it was musical and the most beautiful voice ever. And she said something bt all I could remember were the words you will be filled with knowledge and power. Does this mean anything.
I agree with all the guys above. It's probably your Spirit Guide. Every time you meditate , have a notebook /diary next to you and write down your experiences:) That's gonna help you a lot in the future.Next time you meditate, call upon your Spirit Guide, and ask for her name.
