To add to Puneet’s guidance.
When you charge water with SHIELD OF 7 RAYS , and even if 100 people drink from this charged water container….all will receive 100 percent energy.
Energy gets divided in direct request method. In water method, the medium of energy is water. So there is no division of energy.
Even when it gets divided in non water methods, its important…. like every child and every family member is equally important and the family as a whole needs energy and protection with SHIELD.
So one can choose not to think about energy division, and just request to keep the whole family safe.
