Dowsing with L-rods
L-rods are the second most popular tool for dowsing, after the pendulum. Sometimes they are called divining rods, although that is not an accurate term as the word ‘divining' tends to make people think of some supernatural insight into the future, which is not what dowsing is.
Often people will ask how dowsing rods work. The simple answer is that they work because the dowser is making them move. And that happens because of tiny movements in the dower's hand and arms which are subtle reactions impossible to stop.
With a pendulum, pretty much everyone can hold one so that it dangles below their hand. However, L-rods require a little more sophistication in the way they are held. Because they are rods with handles, they have to be held in such a way that they can move easily to one side or the other, or cross over in front of the dowser. That means they cannot be held too high up, or they will fall back on the dowser, nor can they be held too low, as they will only dangle uselessly.
The ideal position is just below the horizontal. The hands and arms should be as relaxed as possible and still hold the rods easily in that position. If the thumbs are on top of the rods, they simply won't move, so make sure that the rods can swing by making small movements with your arms or hands. When you're happy with that, get the rods back to the start position and hold them steady there.
Most rods come in pairs, but you don't actually need two at a time for most dowsing purposes. So, if you find that one hand is more sensitive, go with just that one to begin with.
To use dowsing rods, you must, as always, have a clear question in mind and then get into the dowsing state which allows the answer to come without your emotions blocking it. For most dowsers, a ‘yes' is when the rod swings inwards toward the body. Conversely, a ‘no' is when it swings outwards. Of course, your response might be different. Practice and see.
Rods are most often used outside for location purposes. When using dowsing L-rods in this way, you need the same precise question and the same dowsing state. Assuming you are walking across some land to find an answer to your question, you will need to decide in advance what will be a ‘yes' for you when you have found it. It could be when your leading foot is over it, when your hands are over it, or even when the tips of the rods are over it. As long as you know what will be the trigger of the response to move the rods, you will be able to locate what you are looking for.
Of course, there's a whole lot more to both dowsing and L-rods, but this should be enough to get you started.
