I don’t know if my methods are similar to others. This is just the way I do it.
Start by being in a very relaxed state. The more relaxed you are, the better.
Have in your mind who or what you wish to see.
Count down from ten to one. As you go downwards, you get closer and closer to a special viewing door. As you say “one”, the door becomes totally vivid and swings open for you.
Step through it and you are in the same place as whatever you wish to see. Close your eyes and still your mind. It is very important that you not imprint anything on your perception. This is where meditation comes in handy; you need to be able to make your mind shut up and perceive.
You may see colors, shapes, or scenes like little movie clips. You may hear or see words. You may get a sense of the person’s environment. It is much more likely (imo) that this will take place in your mind, as opposed to your senses; so your eyes may not see a color, but your mind will show you a color using the faculty of imagination.
Observe your target for as long as you wish. If you don’t get anything, don’t worry. It takes practice.
If a person or place has certain protections, they may be impossible to View.
When you are done, step backwards out of the special viewing door. Close it firmly. Count from one to ten.
The less you know about your target, the better. Everything you know about a person could invade your conscious mind and distort the real Viewing.
