When you charge water and things , they remain charged till they are consumed. Water and things are medium to receive energy.
When you place a direct request or send energy through name on paper or on photo of a receiver like a person or situation….the energy is also consumed by the person…so there is demand and supply of energy BOTH happening.
So when you keep it aside you allow the receiver ie person or place to receive energy. VK is attuned to send energy for maximum 30 min for one request. After that VK remains idle for next request.
If a person requests PAIN CARE SERUM for XYZ and Xyz gets relief in 10 min. Then you can break the previous request and place a new one.
However if there is a wealth healing or chronic illness healing allow VK to send energy atleast for 5 min and upto 30 min.
Imagine there is a reservoir which is created for receiver and VK keeps sending energy for receiver in reservoir. The same reservoir also has a tap where energy is released and consumed by receiver. So supply should continue for around 30 min as VK can send energy upto 30 min.
