These might be counted either as prayers or spells and need a passionate concentration on bringing, for instance, peace of mind or healing to the recipient.
They hold no danger for the practitioner but are sometimes more difficult to appreciate since they tend to be more general than other types of magical work.
They may be thought of in terms of a positive energy from beyond the practitioner, being channelled towards a specific purpose.
Saying grace before a meal is a form of blessing preceded by an offer of praise and a prayer of thankfulness, an acknowledgement of a gift.
The food is enhanced by the act and the blessing is given by drawing on the power vested in the knowledgeable expert.
Thus one practitioner may call on the nature gods whereas another might call on the power of Jesus Christ.
