I just started a new cards course on compatibility at https://www.cardsoftruth.com/courses/advanced-courses/birth-card-compatibility.
This will be a lengthy and involved course during which you will not only learn about compatibility, but a lot of important things about the Sun, Moon, Mars and Venus cards.

Today I started a new cards course on Event Spreads. An Event Spread is a birth card spread calculated for the moment that an event takes place. Reading the Event Spread will reveal what that event has in store for the person. Principles of Event Spreads can also be used to select favorable times to begin an event. You can see the course at https://www.cardsoftruth.com/courses/auxiliary-courses/event-spreads.
