In
L.D.S. parlance, this term can be used generically to
refer to most any prayer, particularly prayers before meals, meetings,
activities, etc.
The term is often used specifically, however, to refer to an ordinance of the
priesthood whereby hands are laid on a supplicant's head and a
pronouncement of health, comfort, counsel, or christening is made. Though
the syntactical structure of the blessing is similar to that of a regular
prayer, the words are directed to the recipient rather than to God, often with
instructions such as "be healed" or "live worthily" or "remember that your
Father in Heaven is mindful of you."
The giver of a blessing of this sort must be a worthy priesthood holder, and
he is directed to keep his mind open and not speak his own thoughts or wishes,
but rather to listen for the promptings of the Holy Ghost in knowing what
instructions and/or promises to pass along to the recipient.
When giving a blessing, the spokesman may be assisted by one or more other
priesthood holders, who stand shoulder to shoulder and also place hands on the
recipient's head. It is useful for the recipient to have strong neck muscles.
The efficacy of a blessing is supposedly predicated on some arcane combination of the
faith and righteousness of the givers and the receiver -- which makes for a
handy straw man in cases where the blessing fails to come true. This can, of
course, damage the recipient's self-worth, but hey -- it's a Church for the strong.
