The above comment is based my real personal experience.
My mother had some back pain problem and i gave her VK to rotate and rub on the affected area with request.
After nearly 2 months she had no relief than i observe this and make her to drink charge water along with it.
And within a week time she felt much better and in a month time got healed completely.
i respect your time for personal working and busy schedule, but if you can please charge Water once for whole day
then it will give her more boost.
You can charge her water directly or image of water filled bottle also.
Also must read the links shared by Rakhi didi for amazing guidance.
