Have you ever done a linear Lenormand spread (such as a 5 card spread) where you picked a card to act as the focus card?
Or maybe you've charged a card to “activate” it in an attempt to make your reading more accurate?
While there is nothing wrong with either of these techniques, the use of a focus card doesn't actually enhance your reading.
How a Focus Card is Limiting
You can get accurate answers when you use a focus card, but the reading will not be as full and well-rounded as readings that don't use focus cards. A lot of key information will be left out.
Think of it like this.
When you read a Lenormand spread, you tell a story with the cards. Each card adds a bit of information. Each combination fleshes out details. A focus card removes an element of the story.
Instead of allowing all the cards to come together to answer your question, with a focus card, you're pre-selecting a card and placing it smack dab in the middle. It doesn't give any information. It doesn't answer the question. No insight is gleaned.
However, if instead, you omit the focus card and draw all the cards for the spread as they come, each card will have meaning.
Each card will have details, insights, and little tidbits.
Together they will give you a full and broad analysis of the situation.
Something that a focus card can never do.
And as for activating a card to make your reading more accurate?
Nonsense. It's not necessary.
The cards will answer your question whether or not a card is activated.
The accuracy of the reading lies in the skills of the reader, not in imbuing special powers into a card.
