You may have seen a blessing being given or heard about this. A blessing is essentially a form of energy healing or energetic transfer of divine energy. Every blessing is different, depending on your needs at the time.
The intention of the person giving the blessing to get out of the way to let the Divine flow through them to assist the person receiving the blessing. Essentially it is the energy of the Divine, flowing through a divine channel (the person blessing) to awaken more divine in the recipient of the blessing.
Sometimes a blessing is about helping a person to expand their awareness and consciousness, sometimes a blessing is about helping the person let go of old stuck energy and sometimes a blessing comes through as unconditional, Divine love for the person being blessed to help them realise they are loved unconditionally by the divine. There are as many flavours of blessings as there are people in the world; the goal is to spiritually uplift the person being blessed and give them an energetic boost to transform and lift their life.
The person offering the blessing may place their finger on the ajna chakra (the energy centre between the eye brows) or the palm chakras in the hands (that link via energy meridians to the heart chakra).
Those receiving blessings may experience tingling, rushes of joy, crying, laughing or even physical shaking as energy moves. The best thing to do is remain receptive, open and appreciative and try to clear the mind by just thinking ‘thank you.’ If you are in the room when someone is receiving a blessing, the best thing to do is send them love as this actually helps them and also some of the blessing will flow to you.
