Technique of Intention
The practitioner enters astral projection only through an intense and focused intention of immediately experiencing astral projection. Alternatively, this may also be a calm but constant desire felt over the course of the day. Intention is especially effective not only during an attempt or long before one, but also every time you fall asleep, as this moment can be taken advantage of using the direct or indirect method.

That is my favorite method. I got this information from here:
