Finding Your Inner Elf
It may be that you wish to allow your elven side to strengthen, and also to be in a state of mind that allows you to re-discover memories and knoweldge that you may have forgotten through intervening lifetimes.
One website that suggests various techniques is here at the Lostkin Project I have to say that personally, I have not tried these. So, here is my way of exploring memories, knowledge and feeling.
Rialians website also has an image that can be used for meditaton: http://www.rialian.com/portal.htm
I find that certain sounds and visuals help get your mind into the correct state. I find that medieval music - for example that by the Medieval Baebes (a personal favourite), and some drumming (shamanic, not a set of drums for a pop concert) helps a great deal. That, and maybe a film which while not Elven will certainly put images of landscapes that resonate on a subconcious level into your heart - leaving aside some passages of Lord Of The Rings, I use such diverse films as The Sword Of Xanten, Eragon, and Dragon. There is an obvious danger here, make sure that memories you get are not born directly of your most recent viewing of DVDs!
Being out in nature is a very good way also of connecting with more natural energies that are healthy for elven souls. Make sure you are comfortable, dont neccasarily load yourself down with all the latest expensive walking gear, that defeats the whole object of the excersise. Free yourself as much as is possible of the cloying materialistic energy of this world. Travel light, take water and some natural organic food that you like. I will often head out in my usual medievally style (thats how I prefer to dress) gear, and in summer flip-flops. This isnt a case of a high speed rush from here to there. You will know if you are more drawn to the sea, mountains, moorland, forest, etc. Dont feel that you need to take someone with you (although, it is usually sensible to let someone know where youre going, and to take a phone with you! And if you need to take a map and compass, do it!). Dont worry about "Getting Back For Dinner On Time". Wander the paths, explore, stop in places that you find beautiful, and learn to feel thier energy. The auras of trees and creatures, the difference in the energy of different types of terrain, and then even the personal energy of a certain space - this is how I have found fairy groves, and energy vortices. Take something creatve to do as well if you want - some paper to write or sketch on, a small camera (I repeat dont load yourself down with stuff) if you prefer to take photos, a drum.... Meditate, and take time out of the rat race. Try to avoid areas of massive crowds or urbanisation, as much as is possible, on your return.
The Elven state to me, is much calmer than a human state, calmer, instinctual, honest, and free. :)
Dreaming and meditation..
Most of my direct visual memories have come as dreams and flashbacks, of thier own accord. I have not yet learned how to increase them or focus them at will, but where you have a memory, or something that you are pretty sure is a memory, come as a dream or vision, there is one method that may allow you to explore it further. Relax totally, in a position and place that is comfortable for you and where you will not be disturbed. Go back to a key scene in the memory or dream. Visualise it unfolding again, and allow it to continue unfolding in your mind, after the original dream or vision ended. Do not try to conciously direct it or change it, simply allow it to flow through your mind, and events to unfold. If you have spirit guides, ask them also if they can teach you anything about your memories or your elven self... But also bear in mind any warnings they may give. For example, I (re)discovered my Elven soul song, a few weeks before writing this web-page. My spirit guides told me very definitly that the song must not be sung "in public" or recorded. I paid total attention to that, but did not understand why. It was not until yesterday, in discussions on forums elsewhere, with others, that I learned why. That if a malicious person learned someones soul song, it could have dangerous results for you. What I mean to point out by this, is to pay attention to spirit guides, and gut feelings about what you should "share" and to whom.
Other than that, while exploring any past life means that you have to realise you could discover ANYTHING about yourself, nice or not, traumatic or not, it is a wonderfully positive experience, and really helps you understand more about who you are now.
