Internet is the right place to gain insight on this topic as there are hundreds of people who have already shared their knowledge and experience on how to listen to the inner voice which is also called intuition.
Before reading their spiritual development articles, you might want to know the benefits of acting as per your intuitions.
* It tells you what to do and when to do.
* It urges you to act at the tight time.
* It warns you before you say something or do something which might not be in the best interests of others
How important it is to listen to your inner voice?
* It is always for your good and happiness
* It never lies
* It always guides you to act that can bring peacefulness to your mind
Intuition is available to every human being irrespective of educational level or social status. It comes from within.
Are there any e-books that teach you how to develop your intuition?
I was recommended an e-book titled, "The beginners' guide to develop intuition".
I have not read it to write a review. I request you to search for reviews of the e-book before you buy it.
