Energy and Hands

​Channeling energy through one’s hands is a basic practice for witches, healers, and other energy workers alike. This practice is as natural to us as breathing and there is no right or wrong way to do it. It all comes down to whatever feels “right” or natural to you. That said, one thing I keep hearing is that the flow of energy during magical work is “in to” (received by) the nondominant hand (usually the left), and “out of” the dominant hand (usually the right)*. I have read this theory in numerous books. It is quite popular in witchy “how to” books. While this does sound practical, it isn’t going to be the case for everyone. Recently I watched a video regarding the meaning of itchy palms which basically stated that the right was your receiving hand and the left was the  power hand. Again, this may be the case for some, but not all. My issue with either theory is two-fold.
My first issue, as I stated above, is that it is really about what feels right for the individual. Each person would have to discover for themselves what works for them; experimenting with how energy feels, how it flows within and through themselves. Many print and media sources give channeling instructions as if they are the way things are done. This is very misleading to new practitioners.
My second issue is that, as any energy healer can tell you, energy flows through them and out through both hands. Energy healers also run hands over a body to find temperature or energetic discrepancies that may be locations healing energy needs to be focused on. That would imply that either or both hands can be used to receive and direct energy. While it is possible one hand may be more efficient at either task, both are capable. If you have learned an energy healing modality like Reiki or chakra healing you may be aware that there are many chakras (energy vortexes) in the body, including in the hands. Energy is said to move both into and out of the chakras, which supports this as well.  
I guess my issue over all with this kind of thing is how information is passed to new practitioners or curious people as though that is the way it is. I do not agree with that myself. It has been my experience that working with energy for any reason is a personal thing. While basic general knowledge can be passed to get one started, experience is really the best teacher. One should take everything they read or learn with a grain of salt and trust their instincts/intuition.
What have you been taught? Do you generally favour channeling in one hand and out the other? Did you figure it out for yourself, or were you taught the way that works for you? 
 
*Note: These theories have nothing to do with energy vampirism, which is an entirely separate topic I may touch on another time. This is about channeling, not feeding.
