How do I have an OBE/Astral Projection
There are many techniques to induce an OBE. You should try as many of these as you can. Visit this page to see lots of methods:
You want to ideally spend at least 30 minutes a night for a week on each technique before moving on to the next. When you find one is more successful than the rest, spend a little extra time developing that method. When you find your best technique, stick with it!
While some people can project out of their body the first time they attempt it, you should count on it taking at least a month. 30 days seems to be the average for most people to achieve success.
