Ideally, your meditations and other routines should remain the same for all the duration of the square, so that you have the most stable energy output. If you raise your energies by vibration before the square, you must do this every day for the duration of the square, and also for the same number of repetitions and so on.
When you do a square, you must separate this as a working and do this with exclusive focus, etc. In both cases, the square will be valid, but there are ways to amplify this magic and make it geometrically perfected.
