I never did Radki and only found out about it on the forum. Honestly, I have formulated certain energy work around the anime idea, but one must look at what preceded anime- qigong, tantric yoga, martial arts, myths and legends, religious stories, etc. All this anime stuff is based upon ancient practices, albeit with creative intellect and intuition (which is what practical methods of energy work, martial arts, fitness or magic should incorporate to be most effective for the individual).
I am a big fan of Dragon Ball Z and have found correlations between the show and energetic practices. I think if we look at the ancient teachings, the possibilities of them in the modern world and how to enhance them with traditional and personal methods (this is what psi represents to me) then seeing their potential from a fictitious point of view (or what Alan Moore calls the Immateria- or plane of imagination where all things are possible and can be real, but it depends on the will of the mage or psion) we can devise our own plan of action, or our own theories and techniques for pragmatic results.
For instance, tying in the seven Dragon Balls as the Seven Chakras, Shen-Ron (the wish fulfilling dragon) as the Kundalini. Super Saiyan transformation as the Golden Body (Rainbow Body, Diamond Body, etc), flying as light air kung fu (yes, it is real. There is actually a good post with a video link on Veritas somewhere). There are many, many anime/comic book powers that are real, but not to the extent that we may want them to be. I have never seen or experienced any telekinetic ability that I can prove being so, but I have had extra sensory perceptions via mind linking, reading, future seeing, spirit encounters and magical projection and achievement. I use these indicators as ways to understand that the human brain and body (along with the mind, or higher/subconscious functioning of our innate selves) have capabilities beyond our understanding.
Sometimes fiction gives us that extra boost to want to develop and heighten our perceptions, magical, energetic and martial skills. Myths and folklore about the Greek Titans, Gods and Heroes, to martial arts myths about Karate and Kung Fu masters have all given me aspiration and hope on this long journey of discovering my self and human potential. Myths and religious stories are nothing but ancient forms of fiction and we read these stories and (some of us) view them as real- the supernatural abilities, the divine connection, etc, so why is it so bad to come up with a new paradigm that uses modern stories fused with ancient and modern techniques of the Force, Super Saiyans, Namekian fusion and healing, contracts to have specific psi abilities, etc, as a means of physical, emotional, spiritual, energetic and magical well being and ability discovery?
From what I have experienced with my experiments into magic, psi and energy work, as long as your intention is strong enough and you know your body and mental states well enough that you can heal any blockages/deviations or know the sensations and processes before they get too bad so you can reverse them, any model of energy, magic or fitness you choose can be lasting and beneficial to your life and loved ones. Like mentioned earlier, you need a good balance of traditional understanding and practice (this is where master teachers [Guru, Sifu, Sensei, Mage, etc] are priceless) mixed with a good balance of intellect (Scientific Method) and intuition for the best results on the path- whether it is for spiritual or ability gain. I personally use it for both.
