After completing the four preliminaries, visualize a lotus seat an elbow length in front and also above our head; Sakyamuni Buddha is seated on the lotus; the Mahayana bodhisattvas and Theravada sangha revolve around in the four directions; the Buddha and all the bodhisattvas and sangha are facing us.
Then, in front of Sakyamuni Buddha, offer the seven-branch prayer of The Aspiration of Bodhisattva Samantabhadra. Visualize as you recite the verses, which is the proper way to conduct all practices that contain recitation. This is to remind us to reflect on the meaning of the verses. If we recite the verses without connecting with their meaning, it is not very helpful to our practice, just a virtuous deed.
Following this, generate strong faith in the Buddha and bodhisattvas, and supplicate to them with genuine devotion: please grant me blessings to complete the practice of the Four Dharma Seals in this sitting.
