The Celtic Cross is one of the most well-known tarot spreads, made up of ten cards arranged in a cross-and-staff pattern, with positions often representing the present situation, the immediate challenge, the conscious and subconscious influences, the past and near future, and finally the person's attitude, external influences, hopes/fears, and ultimate outcome. It's generally used for in-depth exploration of a complex question or situation, offering a layered, multi-angle read that weaves together timing, psychology, and external factors rather than a quick or narrowly focused answer.
