As you are using VK to send energy ….you are already a COSMIC HEALER.
It is best to mimic other healing modalities through VK as VK sends pure energy. And the sender is VK not the VK user so its safe.
Now about how many VK….it depends on how many receivers you want to send energy, what is the situation and how much is the severity or energy need.
If you have many receivers to send energy to….remember that you should also wear VK most of the times for your own benefit and protection.
The advantage of having multiple VK is that you can BOOST each healing by the BOOST method….energy multiplies more fold.
There are VK users who use from 3 VKs to even 12 VKs to heal multiple people. One also needs to chalk out easier and convenient ways like charging drinking water….so that VK remains free for more requests.
Request your VK to MULTIPLY with your wish of healing multiple people….you may get a signal to take more VKs…
