Hi menk1,
Tuning into the ley lines would be an amazing thing. First step, going outside and leaving the computer behind... that always seems the most difficult.
I became a reiki master just over a year ago. It has been so amazing to watch and feel the energy spiral through my life and alter every aspect of my experience.
Sweeping changes became quite frequent, and each has lead me out of certain situations/environments that were toxic, but i believe i got into them to learn the lessons that i needed to be able to connect with the energy on even deeper levels.
I used to have pain in almost every join of my body, from an auto immune condition and cartilage damage... Becoming attuned to reiki helped me get rid of all of my pain. I started skating again, and when my knee's got too painful, i'd just sit down and channel energy into them... it is as if my pain became my breath, and i could breath it away.
I love doing energy work with very skeptical people, especially when they have physical pain to deal with. Some of them have freaked out when they start to feel the tingles coming through me, but they are amazed that there can be a truly tangible sensation... not to mention their pain goes away.
An old room mate had hit a wall in regards to an assignment, and she just couldn't go any further, and was really beating herself up about it. I told her to come outside and i'd help her out... after 5 minutes or less of me channeling into her head, she said that all of a sudden, her overloaded brain started just doing one thought at a time, and she immediately knew exactly what to write for her assignment. 15 mins later, her assignment was done and she couldn't stop thanking me.
Recently, an opened minded, yet skeptical person i barely knew, agreed to let me channel with him, because he had a terrible knee that kept dislocating... That night he gave me biggest hug i have every received... He said "last week, if you had of told me that you could change my life by putting your hands on my knee, i would have told you to get lost, but now i can't imagine where i would be if i hadn't met you". He had a very emotion experience with the energy, and said he felt like he was an hour glass full of sand, and that the sand was draining into me.
I often don't like to give people expectations of what they may experience, so it is always fun when they ask what that tingling sensation is or why there is such intense heat coming from my hand.
HAHA, one day i had gone to see my father who had a spinal fusion and a recent heart attack... He is doing well though. He was eating breakfast, so instead of hugging him I just patted him between the shoulder blades, move my hand bank and forth a few times and held my hand there. He says "your hand had a tremor, it's vibrating", i said "my hand is perfectly still

" to which he replies "oh is that this energy stuff you used to talk about"... it was quite a funny experience.
I believe that we can attune ourselves, and don't need to be facilitated by a master. I did my first two "levels" through a master, but then found the book Radical Reiki Radical Life (downloaded the pfd for free somewhere)m and did the self attunement. The difference was incredible. My best friend is also a master, and we have done attunements with eachother, redoing the reiki ones and also with some other energy systems.
A lot of people think that you need to believe in this stuff for the attunement to be successful, but that certainly was not the case for me. The only way i became convinced that it was real was because i could bring about sensations in myself that i had never dreamed existed, not to mention other people could also have these experiences through me.
Anyway, feel free to ask any specific questions.
Love and Light
