Before you interpret a single reversed card, count them.
The proportion of reversals in a spread is information in its own right, and it is available to you before you have done any interpretive work at all.
Reading the Proportion
Mostly upright. Energy is moving outward and visibly. Things are in motion. This is not the same as things being good — an all-upright spread around a difficult question often means the difficulty is fully in play and cannot be avoided.
Roughly balanced. The ordinary case. Read normally.
Mostly reversed. Something is obstructed, interior, or unacknowledged. Before you read individual cards, you already know the shape: this is a situation happening under the surface, or one where very little is currently moving.
All reversed. Rare enough to be worth naming aloud. Usually either a querent who is deeply stuck, or a question that is not the real question.
Say It First
If the proportion is lopsided, open the reading with it. "Almost everything here is reversed — before we go card by card, this is a spread about things that aren't moving." The querent will usually confirm or correct it immediately, and you have oriented the whole reading in one sentence.
Decide Your Method Before You Shuffle
Readers create reversals in different ways: rotating half the deck, cutting and flipping, shuffling on a table. Some readers do not use reversals at all, and that is a legitimate practice.
What matters is deciding before you shuffle.
A reader who decides mid-reading that "this one reads better upright" is not interpreting; they are editing. It happens unconsciously and constantly, and it is the mechanism by which readings quietly turn into whatever the reader already believed. Pick a method, apply it, and let the spread say what it says.
When You Do Not Use Reversals
Reading upright-only is a coherent choice, and many excellent readers make it. The card's difficult aspects do not disappear — they are read from position and neighbours instead.
The Sun in what blocks you is doing the work a reversed Sun would do. If you go this route, lean harder on position and dignity, which are doing the load-bearing.
