The large number of various kinds of meditation may be confusing when searching for a way. There is not really any "wrong" or "right" method, because there are many paths to the goal. Meditation is not a prerequisite for the spiritual development, but one of many tools.
However, meditation is a very effective tool, and has been used in different ways by many humans in various parts of the world for thousands of years. Its use has been especially common in the so-called "eastern" religions. Today, many people in other parts of the world are beginning to recognize the value of meditation. In a broader sense, religious songs, mantras and prayers are a special form of meditation.
Whichever form of meditation is chosen, it involves going inside, finding the self, meeting the true being. Some methods try to put thought aside to reach a level of consciousness above the mental level, while others involve guiding thought to reach higher levels. Each method has its own advantages, but it appears to me that guiding thought to reach a higher level of consciousness would lead to a higher "thought-free" level, and is easier to master. There should not be any attempts to force yourself to stop thinking. When thoughts come up, they should simply be observed, and with some patience and practice they will be less and less.
Of course everyone needs to find the right meditation technique for oneself. To give you a recommendation - not a general rule -, "light gate" or "light tunnel" meditations are advisable, as stepping through light in a meditation has a cleansing and vibration raising effect, which is the ideal beginning for a deep meditation. This is accomplished by beginning with the triple light protection (see Chapter 4.1), then stepping through a gate of light or a tunnel of light. On the other side you find yourself at a beautiful place, a mountain or a meadow, a river or a beach, or whatever may appear, where you can meet with your spirit guide and/or guardian angel.
You should be the one to decide which method of meditation is best for you, let your heart be your guide. It may be that you change the method a few times, but don't simply "try out" a number of methods. Decide with your heart, and when an inner change urges you to switch to another method, then follow your heart.
Wherever and however you may be meditating, always remember to use the triple light protection. Then you will find the right path and promote your spiritual development.
