Start off by listing several purposes or goals that you have for yourself. Select one that seems important to you now. Create a symbol to stand for that goal. With that symbol in mind, close your eyes. Notice that a big field stretches in front of you.
Some distance away is a mountain.
On the top of the mountain you can clearly see the symbol that stands for your goal. Leading up to the top is a straight path. Experience yourself as having the strength to make the climb and achieve your goal. As you start to ascend, you become aware that there are entities who are trying to stop you. They may use all sorts of methods - make you feel guilty, argue with you, seduce you, threaten you, lure you with promises, etc.
