This is different than healing or helping Human Beings heal themselves. Wild animals do not have a Karma that is similar to people in most cases. Their healing (at least for me) goes pretty well. Pets can have Karma though as theirs becomes wrapped up in the Karma of their Human friends. These come as teachings of love and loyalty and the ability to let a dear friend go if that is the case.
It is best to have the person who loves them most initiate a healing process for them. Love and intention are the tools one uses. There is no permission needed only love and the confidence of knowing it can be done. Then allowing it to be done. You provide the intention and the energy and the love. Kundalini will determine the "how".
When I was learning this I used to practice on anything. Bugs, spiders, birds, my cat, dogs, horses, it didn't matter. Fish too as they are so delicate and intelligent.
There is a consideration that is similar to karma for animals though and that is the natural instinct of the creature. The natural processes of the animal needs to be honored and if that entails the death of that animal then that death must be honored.
I remember healing a black widow spider one day on a ranch in Zamora California. It was in the well house and it looked hurt so I initiated a healing process upon it. Well the spider started screaming. It was weird and kind of shocked me as before that I had never heard a spider scream. Since then I have heard them scream. Some species scream when they are hunting.
Its mate up on the wall of the well house heard it and started coming down the wall towards it and me! Almost immediately I could tell I was interrupting a natural process as the black widow spider gets its name for how the reproduction process occurs for them. My interference wasn't appropriate and when one is working with wild creatures these instinctual natures must be honored or you can be put in peril.
I stopped the healing process on the spider and re-evaluated my understandings of these issues. They are fellow mortals and have their own path to follow all of them including bacteria and viruses. They have their way of being. So it is with the wild creatures.
With the beloved pets it is different one can begin a process in them but one must be able to have the discipline of accepting the loss of that beloved pet as well. Part of their teaching for people is the gift of absolute and unconditional love. A loyalty that is very strong and a bonding that crosses species barriers.
So one can allow and radiate a frequency of Kundalini into the process of healing and helping to heal an animal. Typically through the hands though not only through the hands. I did long distance of my cat successfully. One needs to merely ask for it to occur. Ask the Kundalini and follow the impulses that will come. Then surrender to those impulses. - blessings - chrism
