Appreciation is a feeling or expression of admiration, approval, or gratitude towards someone who did good to you or helped you. Appreciative mind is a very important virtue anyone can have. It opens doors for more blessings. Many of you do not understand this. Some completely ignore it deeming it not necessary. Ask them and what they will say is that after all they paid for the services they got. This is not right.
It is true that you paid for the services. But claiming because of that you won't appreciate will only limit your blessings to the exact thing you paid for. The spiritual forces behind the person through whom your problems were solved will not be happy with you. They may decide to block any other blessings outside the service you paid for that may attract others alike. And this may also create a rift between you and the instrument of help to you being the spiritualist that helped you.
